It is a built-in method that returns the encoded version of a string. Is there an equivalent of 'which' on the Windows command line? but the way you used it is the poit. Where does the idea of selling dragon parts come from? How can you find and replace text in a file using the Windows command-line environment? When you don't want to import functional interfaces from a module, you usually supply () to its use statement. The following methods implement this incremental parser. JSON is a data format that is gaining popularity and used extensively in many AJAX-powered Web sites benefits of being it's human-readable. This function has been That means you can only use this function to look at or manipulate text before or after complete JSON objects, not while the parser is in the middle of parsing a JSON object. Care has been taken to make all flags symmetrical with respect to encode and decode, that is, texts encoded with any combination of these flag values will be correctly decoded when the same flags are used - in general, if you use different flag settings while encoding vs. when decoding you likely have a bug somewhere. If your text is not encoded in ISO-8859-1, you do not need this function. Code An online, on-the-fly UTF-8 encoder/decoder. WebJavaScript UTF-8 encoding and decoding with TypedArray Raw utf8.js // This is free and unencumbered software released into the public domain. UTF8 is compatible with ASCII; UTF8 able to convert to other charsets easily by ICONV. If your string to be converted to utf-8 is something other than iso-8859-1 (such as iso-8859-2 (Polish/Croatian)), you should use recode_string() or iconv() instead rather than trying to devise complex str_replace statements. Typical names for the single object key are __class_whatever__, or $__dollars_are_rarely_used__$ or }ugly_brace_placement, or even things like __class_md5sum(classname)__, to reduce the risk of clashing with real hashes. If you haven't guessed already: If the UTF-8 character has no representation in the ISO-8859-1 codepage, a ? WebThe utf8_encode() function encodes an ISO-8859-1 string to UTF-8. It must return a single scalar that can be directly encoded into JSON. Perl array references become JSON arrays. WebJavaScript Object Notation also knew as JSON. The following methods are for this module only. This completely resets the incremental parser, that is, after this call, it will be as if the parser had never parsed anything. // Reads a file story.txt ascii (as typed on keyboard). fr Webservice-Security/WSS4J compliancy) you might use this: Avoiding use of preg_match to detect if utf8_encode is needed: I recommend using this alternative for every language: This function I use convert Thai font (iso-8859-11) to UTF-8. the separator. Latest version: 3.0.1, last published: 4 years ago. With kanji mode is possible to encode characters from the Shift JIS system in an optimized way. Why does the distance from light to subject affect exposure (inverse square law) while from subject to lens does not? Users can also Javascript pretty print the Javascript file by uploading the file. Optimal, reliable with Powershell. ; Select ASP.NET Core Web Application.Name the project WebApp1 to have the same namespace as the project download. This tool saves your time and helps to encode Hyper Text Markup language data. If TO_JSON returns other blessed objects, those will be handled in the same way. However, it is not always possible to transfer a Unicode character to another computer reliably. When using XMLHttpRequest or another AJAX technique to submit data to a PHP script using GET (or POST with content-type header set to 'x-www-form-urlencoded') you must urlencode your data before you upload it. will be returned. Perl hash references become JSON objects. . Defined by the Unicode Standard, the name is derived from Unicode (or Universal Coded Character Set) Transformation Format 8-bit.. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte (8-bit) code units. Click on the URL button, Enter URL and Submit. If you want to pass a url with parameters as a value IN a url AND through a javascript function, such as " 255) will be encoded as such characters, and likewise such characters are decoded as-is, no changes to them will be done, except "(re-)interpreting" them as Unicode codepoints or Unicode characters, respectively (to Perl, these are the same thing in strings unless you do funny/weird/dumb stuff). Why does the USA not have a constitutional court? See "SECURITY CONSIDERATIONS" in JSON::XS for more info on why this is useful. If $enable is true (or missing), then the encode method can convert a non-reference into its corresponding string, number or null JSON value, which is an extension to RFC4627. If you are looking for a function to replace special characters with the hex-utf-8 value (e.g. For more information on module installation, please visit the detailed CPAN module installation guide. This only works when a preceding call to incr_parse in scalar context successfully returned an object. Not the answer you're looking for? These mappings are designed to "do the right thing" in most circumstances automatically, preserving round-tripping characteristics (what you put in comes out as something equivalent). For details, see each backend module you use. WebIf you click the "Submit" button below, the browser will URL encode the input before it is sent to the server. JSON::XS and JSON::PP objects are quite different (JSON::XS object is a blessed scalar reference, while JSON::PP object is a blessed hash reference), and can't share their internals. Please note that utf8_encode only converts a string encoded in ISO-8859-1 to UTF-8. Other blessed references will be converted into null. JsonSerializable JSON. Blessed objects are not directly representable in JSON, but JSON::XS allows various ways of handling objects. Kanji mode. On the Perl level, there is no difference between those as Perl handles all the conversion details, but an integer may take slightly less memory and might represent more values exactly than floating point numbers. This tool saves your time and helps to decode link data. WebThat is, utf8_encode is a specialized case of character set conversions. They are terminated by the first carriage-return or line-feed character, after which more white-space and comments are allowed. htmlentities() or About this tool. Do not let the browser auto encode an invalid URL. UTF8 support many languages. encode_json and decode_json are exported by default. Note: The below scipt is an Independant Subprogram. If the code points are all the same size, measurements of a fixed number of them is easy. In most cases it is OK to use url_decode() function but not if you've got UTF characters in the strings. Encrypt password section of winrar command line, Batch file to delete files older than N days. Converts the given Perl data structure to a Unicode string by default.

Sudo update-grub does not work (single boot Ubuntu 22.04). -_. have been replaced with a percent Surprisingly, decode will ignore these flags and so treat all input values as governed by the utf8 flag. Any Unicode characters outside that range will be escaped using either a single \uXXXX (BMP characters) or a double \uHHHH\uLLLLL escape sequence, as per RFC4627. Windows-1252 presenta Simple static class for array URL encoding, #-------------------------------- TEST AREA ------------------------------------, 'Content-Type: text/plain; charset=utf-8', if you have a url like this: test-blablabla-4>3-y-3<6 or with any excluded US-ASCII Characters (see chapter 2.4.3 on, Human Language and Character Encoding Support, http://www.w3.org/TR/html4/appendix/notes.html#h-B.2.2, https://www.notarealurl.com?id=50&name=namestring, http://issues.apache.org/bugzilla/show_bug.cgi?id=34602, https://tools.ietf.org/html/rfc1866#section-8.2.1. and converts to UTF-8. And finally, in list context, it will try to extract as many objects from the stream as it can find and return them, or the empty list otherwise. Basically, this function call is functionally identical to: You can pass an optional hash reference to modify its behavior, but that may change what to_json expects/generates (see ENCODING/CODESET FLAG NOTES for details). This function call is functionally identical to: The opposite of encode_json: expects an UTF-8 (binary) string and tries to parse that as an UTF-8 encoded JSON text, returning the resulting reference. */ echo json_encode(42); // In the end, you need to echo the result. Not the answer you're looking for? So just to save time: Don't use urlencode() or urldecode() if the text includes an email address, as it destroys the "+" character, a perfectly valid email address character. If you need a function which converts a string array into a utf8 encoded string array then this function might be useful for you: For reference, it may be insightful to point out that: Walk through nested arrays/objects and utf8 encode all strings. Use your Javascript REST URL to Pretty Javascript and Print Javascript. This module is a thin wrapper for JSON::XS-compatible modules with a few additional features. This is the most common way of using the method. Nesting level is defined by number of hash- or arrayrefs that the encoder needs to traverse to reach a given point or the number of { or [ characters without their matching closing parenthesis crossed to reach a given character in a string. HEX to Pantone Converter Encode and Decode. Compared to encodeURIComponent(), this function encodes fewer But findaly I decided to write my own code. This can be used to add more text in as many chunks as you want. If an error occurs, an exception will be raised as in the scalar context case. If you do need the previous behavior for better compatibility or for finer control, set PERL_JSON_PP_USE_B environmental variable to true before you use JSON. If that fails, it will try to represent it as a numeric (floating point) value if that is possible without loss of precision. Webutf8_encode ( string $string ): string This function converts the string string from the ISO-8859-1 encoding to UTF-8 .

Many web pages marked as using the ISO-8859-1 character ): I often need to convert multi language text sent to me for use in websites and other apps into UTF8 encoded so I can insert it into source code and databases. CSS JavaScript Minifiers. If the utf8-flag is enabled, encode/decode will encode all characters using the corresponding UTF-8 multi-byte sequence, and will expect your input strings to be encoded as UTF-8, that is, no "character" of the input string must have any value > 255, as UTF-8 does not allow that. Javascript also uses UTF-16 as standard character encoding. Re the previous post about converting GB2312 code to Unicode code which displayed the following function: The following function will utf-8 encode unicode entities &#nnn(nn); with n={0..9}. This function may be useful do encode array keys and values [and checks first to see if it's already in UTF format]: I tried a lot of things, but this seems to be the final fail save method to convert any string to proper UTF-8. This tool uses utf8.js to UTF-8-encode any string you enter in the decoded field, or to decode any UTF-8-encoded string you enter in the encoded field.. Made by @mathias fork this on GitHub! As a special exception, you can also call this method before having parsed anything. Be advised that doskey doesn't work in batch scripts -- only the console. This $coderef is called before the one specified via filter_json_object, if any. A more appropriate name for it would be "iso88591_to_utf8". If the code references returns a single scalar (which need not be a reference), this value (or rather a copy of it) is inserted into the deserialised data structure. WebWelcome to the online JSON Viewer, JSON Formatter, and JSON Beautifier at CodeBeautiy.org. If you want to enforce an array to encode to a JSON list (all array keys will be discarded), use: if you're using ajax to post, and your JavaScript code looks like this: var xhttp = new XMLHttpRequest(); If you have OpenSSL for Windows installed you can use this to encode the string "Hello": The | set /p= is to suppress the newline that echo usually outputs. About Our Coalition. Croaks on error. For example, you can encode control characters Apache Arrow is a development platform for in-memory analytics. This setting can slow down decoding considerably. I have a PHP script that can encode a PNG image to a Base64 string. Visual Studio.NET Core CLI; Select File > New > Project. If you need to know what is used actually, use isa, instead of string comparison. * It all depends on the Content-type header that you send with your AJAX * request. As there is no inherent ordering in hash keys (or JSON objects), they will usually be encoded in a pseudo-random order. This is the documentation of the Python API of Apache Arrow. For example, you can encode Note that a "codeset" is simply an abstract set of character-codepoint pairs, while an encoding takes those codepoint numbers and encodes them, in our case into octets. @dbenham mentioned the undocumented verbs of CERTUTIL. Searching for a string within a long string can for example be done byte by byte; the self-synchronization property prevents false positives. This module uses JSON::XS by default, and when JSON::XS is not available, falls back on JSON::PP, which is in the Perl core since 5.14. Why shouldn't I use mysql_* functions in PHP? If $enable is true (or missing), then the encode method will not barf when it encounters a blessed reference that it cannot convert otherwise. It might differ depending on how You put the data to the db, but try what worked for me: Thanks for contributing an answer to Stack Overflow! This function is useful in two cases: a) finding the trailing text after a JSON object or b) parsing multiple JSON objects separated by non-JSON text (such as commas). JSON is a data format that is gaining popularity and used extensively in many AJAX-powered Web sites benefits of being it's human-readable. sino que asume que est codificada como ISO-8859-1 (tambin conocida como "Latin 1") If $enable is true (or missing), then encode, upon encountering a blessed object, will check for the availability of the FREEZE method on the object's class. Please join as a single line, no spaces, before use. Certainly being nitpicking here but Base64 encoding is not encrypting (and decoding not decrypting). . Making statements based on opinion; back them up with references or personal experience. y la convierte a UTF-8. actual entity is used instead of the desired variable name. Most of this section is also taken from JSON::XS. This is useful when you want to pass a decoded data structure directly to other serialisers like YAML, Data::MessagePack and so on. Click on the URL button, Enter URL and Submit. How many transistors at minimum do you need to build a general-purpose computer? For deserialisation there are only two cases to consider: either nonstandard tagging was used, in which case allow_tags decides, or objects cannot be automatically be deserialised, in which case you can use postprocessing or the filter_json_object or filter_json_single_key_object callbacks to get some real objects our of your JSON. Why is apparent power not measured in Watts? Esta funcin no intenta adivinar la codificacin actual del string proporcionado, Color Converters. encode will not be affected in any way. Ready to optimize your JavaScript with Rust? Returns true if the backend inherits JSON::XS or Cpanel::JSON::XS. esto nunca da lugar a un error, pero no dar lugar a un string til Note that this works only when you decode. Like in JScript / Javascript you can reference a method both by, Thanks! How to print and pipe log file at the same time? fr Webservice-Security/WSS4J compliancy) you might use this: Avoiding use of preg_match to detect if utf8_encode is needed: I recommend using this alternative for every language: This function I use convert Thai font (iso-8859-11) to UTF-8. I'm running PHP version 5.0.5 and urlencode() doesn't seem to encode the "#" character, although the function's description says it encodes "all non-alphanumeric" characters. It seems a manual str_replace is required unless this was fixed in a future PHP version. When you do, the internal JSON::XS object is replaced with a newly created JSON::PP object with the setting copied from the XS object, so that you can use JSON::PP flags (and its slower decode/encode methods) from then on. About this tool. If you click the "Submit" button below, the browser will URL encode the input before it is sent to the server. yes it is, and to be correct you shouldn't use utf8_encode anyway. Note that precision is not accuracy - binary floating point values cannot represent most decimal fractions exactly, and when converting from and to floating point, this module only guarantees precision up to but not including the least significant bit. Use encode() to Encode a String in UTF-8 in Python. They are overloaded to act almost exactly like the numbers 1 and 0. The name of TO_JSON was chosen because other methods called by the Perl core (== not by the user of the object) are usually in upper case letters and to avoid collisions with any to_json function or method. 1 you encode utf8 then json so to get your input you have to decode json and then utf8 teemitzitrone. Of course, JSON does not support this in any way, so you need to make sure your data never looks like a serialised Perl hash. Pretty much the way you show. $copy = $false). &, © and £ are parsed by the browser and the force utf8 might be helpfull too: http://pastebin.com/2XKqYU49. If $enable is true (or missing), then encode, upon encountering a blessed object, will check for the availability of the TO_JSON method on the object's class. I have found numerous ways to base64 encode whole files using the command-line on Windows, but I can't seem to find a simple way to batch encode just a "string" using a command-line utility. If $enable is false, then the encode method will output key-value pairs in the order Perl stores them (which will likely change between runs of the same script, and can change even within the same run from 5.18 onwards). Note: The JavaScript function encodes space as %20. In fact, applying this function to text that is not encoded in ISO-8859-1 will most likely simply garble that text. utf8 controls whether the JSON text created by encode (and expected by decode) is UTF-8 encoded or not, while latin1 and ascii only control whether encode escapes character values outside their respective codeset range. are encoded as plus (+) signs. The mutators for flags all return the backend object again and thus calls can be chained: If $enable is true (or missing), then the encode method will not generate characters outside the code range 0..127 (which is ASCII). Keep in mind that, if you prepare URL for a connection and used the urlencode on some parameters and didn't use it on the rest of parameters, it will not be decoded automatically at the destination position if the not encoded parameters have special characters that urlencode encodes it. I suggest only to use this option to parse application-specific files written by humans (configuration files, resource files etc.). index.php (or whatever the actual page is named like) json PHP truefalse null truefalse null json null Copy, Paste and Encode. (%) sign followed by two hex digits and spaces encoded Why would Henry want to close the breach? WebThe btoa() method creates a Base64-encoded ASCII string from a binary string (i.e., a string in which each character in the string is treated as a byte of binary data).. You can use this method to encode data which may otherwise cause communication problems, transmit it, then use the atob() method to decode the data again. */ echo json_encode(42); // In the end, you need to echo the result. This setting has no effect when decoding JSON texts. This module can optionally sort the hash keys (determined by the canonical flag), so the same data structure will serialise to the same JSON text (given same settings and version of the same backend), but this incurs a runtime overhead and is only rarely useful, e.g. See also the section ENCODING/CODESET FLAG NOTES later in this document. rev2022.12.9.43105. This function may be useful do encode array keys and values [and checks first to see if it's already in UTF format]: I tried a lot of things, but this seems to be the final fail save method to convert any string to proper UTF-8. I want to see if I can use this somehow in my script which has a username= and password= exposed in plain text. This function encode the special character except (, / ? HTML Encode is very unique tool to encode plain html. Is there a verb meaning depthify (getting more depth)? Click on the URL button, Enter URL and Submit. Likewise, decode will croak if given something that is not a JSON object or array. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. : @ & = + $ #) characters. ! Headers are left untouched. If this environmental variable is not set, it tries to load JSON::XS, and if JSON::XS is not available, it falls back on JSON::PP, and then JSON::backportPP if JSON::PP is not available either. Is Energy "equal" to the curvature of Space-Time? Please note that UTF-8-encoded strings do not contain any characters outside the range 0..255, they are thus useful for bytewise/binary I/O. We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Users can also Javascript pretty print the Javascript file by uploading the file. For example, the following TO_JSON method will convert all URI objects to JSON strings when serialised. This worked great when creating a .doc file from Blob. This is true for all modern European languages. Use encode() to Encode a String in UTF-8 in Python. For this to work, there must be no separators (other than whitespace) between the JSON objects or arrays, instead they must be concatenated back-to-back. The following Perl regular expression tests if a string is well-formed Unicode UTF-8 (Broken up after each | since long lines are not permitted here. How do I get current date/time on the Windows command line in a suitable format for usage in a file/folder name? You will also most likely combine this setting with space_after. . See MAPPING, below, for more information on how JSON values are mapped to Perl. They are converted into %uXXXX entities that url_decode() cannot handle. max_size) to ensure the parser will stop parsing in the presence if syntax errors. The main use for this flag is efficiently encoding binary data as JSON text, as most octets will not be escaped, resulting in a smaller encoded size. A page at the server will display the received input. This results in a faster and more compact format. Otherwise, the THAW method is invoked with the classname as first argument, the constant string JSON as second argument, and all the values from the JSON array (the values originally returned by the FREEZE method) as remaining arguments. urlencode is useful when using certain URL shortener services. nodejs javascript polyfill performance js encoder decoder utf-8 npm-package small tiny cross-browser es6-modules node-js node-module nodejs-modules utf8 compact utf8-string requirejs-library Other unblessed references are generally not allowed and will cause an exception to be thrown, except for references to the integers 0 and 1, which get turned into false and true atoms in JSON. This module respects an environmental variable called PERL_JSON_BACKEND when it decides a backend module to use. Example: Parse some JSON arrays/objects in a given string and return them. This means that it sometimes won't stop as early as the full parser, for example, it doesn't detect mismatched parentheses. encoding actually use the similar Windows-1252 encoding, utf8_encode Converts a string from ISO-8859-1 to UTF-8. This tool allows loading the Javascript URL to minify. This was a particular problem for me when trying to open local files with a "#" in the filename as Firefox will interpret this as an anchor target (for better or worse). Windows-1252. When converting this text to a stream of bytes, the special characters need to be encoded with something like UTF-8. Or if you'd prefer a batch + JScript hybrid: Edit: batch + VBScript hybrid for @Hackoo: According to the comments on the question, you can use certutil. In Python, if we want to encode a string in UTF-8, we will use the encode() method. you should add a meta tag for encoding within the html AND you should add an http header which sets the transferencoding to utf-8. This means you need to set resource limits (e.g. If it returns nothing (not even undef but the empty list), the callback from filter_json_object will be called next, as if no single-key callback were specified. To install JSON, copy and paste the appropriate command in to your terminal. It shouldn't matter as long as you treat them as boolean values, but a code that expects they are stringified as "true" or "false" doesn't work as you have expected any more. If your source-file is already utf8 then drop the utf8_* functions. They are converted into %uXXXX entities that url_decode() cannot handle. Example, encode a Perl scalar as JSON value with enabled allow_nonref, resulting in an invalid JSON text: If $enable is true (or missing), then encode will not throw an exception when it encounters values it cannot represent in JSON (for example, filehandles) but instead will encode a JSON null value. These special values become JSON true and JSON false values, respectively. This option does not affect decode in any way, and it is recommended to leave it off unless you know your communications partner. How to Run Linux commands from Python on Windows. Find centralized, trusted content and collaborate around the technologies you use most. into your database. Creates a new JSON::XS-compatible backend object that can be used to de/encode JSON strings. In fact, NO native Javascript function will urlencode data correctly for form submission. semi-colon through the arg_separator .ini directive. If $enable is false (the default), then encode will throw an exception when it encounters a blessed object that it cannot convert otherwise. Is it correct to say "The glue on the back of the sticker is dying down so I can not stick the sticker to the wall"? if you get "unexpected Character" error you should check if there is a BOM (Byte Order Marker saved into your utf-8 json. As a nonstandard extension to the JSON syntax that is enabled by the relaxed setting, shell-style comments are allowed. On second thought this won't do since I'll have to include your script with bat2exe. JSON.pm backend modules trust what you pass to encode method (or encode_json function) is a clean, validated data structure with values that can be represented as valid JSON values only, because it's not from an external data source (as opposed to JSON texts you pass to decode or decode_json, which JSON backends consider tainted and don't trust). The release of this new version owes to the courtesy of Marc Lehmann. WebEncodingUTF-8JavaScript Start using base64url in your project by running `npm i base64url`. You can use this as a full-qualified function (JSON::boolean($scalar)). With latin1 (or ascii) enabled, encode will escape characters with ordinal values > 255 (> 127 with ascii) and encode the remaining characters as specified by the utf8 flag. If you need a function which converts a string array into a utf8 encoded string array then this function might be useful for you: For reference, it may be insightful to point out that: Walk through nested arrays/objects and utf8 encode all strings. we are able to pass this source code to the ajax form submit function by using php urlencode : //get the json source code from the mongodb. You can also use \1 and \0 directly if you want. Are defenders behind an arrow slit attackable? If your text is not encoded in ISO-8859-1, you do not need this function. the detailed CPAN module installation guide, go to github issues (only if github is preferred repository), Makamaka Hannyaharamitu, E tag. I have found numerous ways to base64 encode whole files using the command-line on Windows, but I can't seem to find a simple way to batch encode just a "string" using a command-line utility. Appropriate translation of "puer territus pedes nudos aspicit"? Converts a string from ISO-8859-1 to UTF-8, //Convertthestring'Zo'fromISO8859-1toUTF-8. UTF-32 WebIt is wrong to change a character to an HTML entity reference in client-side JavaScript, since client-side JavaScript operates on the DOM, where entities do not exist. If none of the settings are enabled or the respective methods are missing, this module throws an exception. If you need to encode a data structure that may contain objects, you usually need to look into the structure and replace objects with alternative non-blessed values, or enable convert_blessed and provide a TO_JSON method for each object's (base) class that may be found in the structure, in order to let the methods replace the objects with whatever scalar values the methods return. JSON::XS-compatible backend modules don't encode blessed objects by default (except for their boolean values, which are typically blessed JSON::PP::Boolean objects). Another nonstandard extension to the JSON syntax, enabled with the allow_tags setting, are tagged values. rawurlencode()) in that for historical reasons, spaces This section is taken from JSON::XS. ): I often need to convert multi language text sent to me for use in websites and other apps into UTF8 encoded so I can insert it into source code and databases. What's the difference between UTF-8 and UTF-8 with BOM? If it is disabled, this allows you to decode ISO-8859-1- and ASCII-encoded strings, as both strict subsets of Unicode. Encode and Decode. htmlspecialchars(). It does so by accumulating text until it has a full JSON object, which it then can decode. In most cases it is OK to use url_decode() function but not if you've got UTF characters in the strings. There are situations you don't know your resource's encoding and it comes in random. WebNote that UTF-8 can represent many more characters than ISO-8859-1. node js utf8 encode javascript by adreaskar on Apr 18 2021 Donate Comment 0 xxxxxxxxxx 1 //install using 'npm install utf8' 2 const utf8 = require('utf8'); 3 utf8.encode(string) Add a Grepper Answer Answers related to encode ("utf-8") js How to convert data to utf-8 in node.js utf8 decode javascript utf8_encode javascript If no argument is given, the limit check will be deactivated (same as when 0 is specified).

As this code point lies between U+0800 and U+FFFF, this will take three bytes to encode. Debian/Ubuntu - Is there a man page listing all the version codenames/numbers? The problem is that now, if we set the column encoding back to UTF-8, MySQL will run the latin1 to UTF-8 data encoding for us again and well be back to where we started. The resulting encoded JSON text can be treated as a native Unicode string, an ascii-encoded, latin1-encoded or UTF-8 encoded string, or any other superset of ASCII. This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself. Since version 2.90, stringification (and string comparison) for JSON::true and JSON::false has not been overloaded. This This exploits the fact that MySQL will not attempt to encode a blob. How can I encrypt password in a batch file? I know how to open files, but I'm not sure how to do the encoding. As an example, let's implement a THAW function that regenerates the My::Object from the FREEZE example earlier: The interested reader might have seen a number of flags that signify encodings or codesets - utf8, latin1 and ascii. Beyond that, your looking at mb_convert_encoding() or my preferred - iconv extension. Why is it so much harder to run on a treadmill when not holding the handlebars? All boolean flags described below are by default disabled (with the exception of allow_nonref, which defaults to enabled since version 4.0). If you want to enforce an array to encode to a JSON list (all array keys will be discarded), use: if you're using ajax to post, and your JavaScript code looks like this: var xhttp = new XMLHttpRequest(); So here is a function to do the job fairly efficiently: I was testing my input sanitation with some strange character entities.

For the more enlightened: note that in the following descriptions, lowercase perl refers to the Perl interpreter, while uppercase Perl refers to the abstract Perl language itself.
