A simple website where you type in a string and get a list of all Unicode characters in it, their name, value, UTF-8 encoding (including an escaped string for C or Python or similar language), UTF-16 (to clearly show the UTF-16 surrogate pairs in case of emojis and other non-BMP characters) and Block.
It also displays meaning of CJK characters from the Unihan database, but this is not a translator. No web requests past the original one for the page and data JSON, updates in real time.
If you check the "Add search links" block, the text, codepoint, character name, and block name will become Google search links for given character or block. If you want other search engines included let me know via GitHub issues or email.
To see it in action go to https://frex.github.io/unicode.html. Some examples:
NOTE: precomposed Hangul characters (link 7. above) have no names listed, but the block is listed correctly as Hangul Syllables.
Characters from other blocks (Hangul Jamo, Hangul Compatibility Jamo, Hangul Jamo Extended-A, and Hangul Jamo Extended-B)
have names listed. This is how Unicode zip files list the data about these characters. I might try to do something about it
in the future to provide readings/romanization of syllables for precomposed Hangul.
Use GitHub issues or email if this is important for you.
To deploy this tool yoursef you need the three files:
unicode.html- the HTML with input box and inline JS to analyze the string.data.js- the data as JSON, generated fromUCD.zipandUnihan.zipfiles.blocks.js- the data as JSON, generated fromUCD.zipfile.
All the files and the gendata.py script that generates data.js and blocks.js are in this repo.
To get the UCD.zip and Unihan.zip files, visit
https://www.unicode.org/Public/UCD/latest/ucd/.
You don't need to unpack them, just drop them in same directory as gendata.py
and run it, to generate data.js and blocks.js. The meaning of CJK characters is taken from kDefinition field.
Other tools to deal with Unicode strings, analyze them, convert them, etc. (some of these descriptions might be outdated since I've checked them once in the past, check yourself if you want to be doubly sure):
- https://www.compart.com/en/unicode/ - very comprehensive, has all the data, shows various encodings for the given character, has CJK kDefinition field, and search for character by name (needs an enter press and submitting query to server to search).
- https://www.fontspace.com/unicode/analyzer - updates
in real time, but the first time character appears it takes a split second to load its info. It also
only lists the codepoint of CJK characters, but not their meanings. Provides the link with your input
prefilled but it's not plaintext in the URL (it looks base 64 encoded, which for Unicode input makes it shorter in URL than URL encoding done by browser). Does a request for every update if there are new characters
not previously seen in the input (but this data is cached so typing
abdoes 2 requests, andaajust 1). hxxps://unicodemap.org/search.asp - limit of 1000 characters, splits non-BMP characters (e.g. emojis) into surrogate pairs, doesn't update in real time, has no CJK character meaning. Provides a link with your input prefilled.Dead and redirects to some sports website as of February 2025.- https://devina.io/unicode-analyser - updates in real time, has more info than just codepoint values, fast, but still no CJK meaning data. Until late 2022 it had no way to make a link that leads to the page and has prefilled input.
- https://freetools.textmagic.com/unicode-detector - updates in real time, shows you what characters might cause problems and be encoded in longer encodings in SMS text messages.
- https://www.soscisurvey.de/tools/view-chars.php - requires a click to execute, shows non-printable characters hidden in the string, but nothing else.
- https://www.fileformat.info/info/unicode/char/search.htm - requires a click to excute, can only search one character a time it seems (or you can search by Unicode code for some specific character). Includes CJK meaning.
- https://r12a.github.io/app-analysestring/index.html - requires a click to execute, and does web request to get high res picture of non-CJK characters. No CJK meaning, but for CJK provides Unihan Unicode database link, which has this and other information.
- https://chrome.google.com/webstore/detail/unicode-analyzer/pipjflhdnjcdflbkmoldkkpphmhcfaio - Chrome extension, lots of information provided on the tab that opens for analysis, convenient for existing web page, but to analyze own string you need to edit the URL or get it typed into some input box on another website first. No CJK meaning.
- https://www.branah.com/unicode-converter - no character information or CJK meaning, but converts given string in realtime to many UTF- encodings, big and little endian, percent encoding, etc.
- https://decodeunicode.org - modern and fast German made website, with a nice search, showing blocks, languages (named in German for example Japanese is Japanisch), properties, etc. of the characters, but no CJK meaning.
