Unicode Resources

Created by rebecca with major help from @FakeUnicode

Unicode is a standard “registry” of characters designed to catalogue all the world’s writing systems and serve as a superset of all previously-existing character sets used and supported by just about everyone and all their software. Get into the details on Stack Overflow or see some of the Unicode encodings on Wikipedia.

Charts and character data

PDF charts on — The only complete and perpetually up-to-date reference.

List of Unicode blocks on Wikipedia — Also available as a TXT file on

UNIDATA on — “This directory contains the final data files for the Unicode Character Database, for Version 8.0.0 of the Unicode Standard.”

CopyPasteCharacter — Contains a bunch of common characters for easy copying.

Proposed new characters on

Unicode planes reference — Confused about what “BMP” means? Check here.

String analysis

Unicode Inspector — By @timwhitlock, displays the codepoint, byte breakdown, block, symbol, name, and surrogates for each character in a string.

Scarfboy search and string analysis

Understanding UTF-8 on jsfiddle — By @FakeUnicode on Twitter. Displays binary/hex breakdown of strings of text.

What Unicode character is this? — By BabelStone.


Scarfboy search and string analysis — Powerful search engine with previews in Unifont


Shape recognition

shapecatcher — Recognizes Unicode characters through a drawing field.

Kanji search on — Find kanji characters by their parts.

Handwritten kanji recognition — Like shapecatcher for kanji.

Google Translate — Click the pencil icon in the input area to enable shape recognition. Great for writing short bits of text in a language you don’t know.

List of proposals and their associated codepoints on Wikipedia

Possible upcoming emoji on

List of emoji ZWJ ligatures on — Note: These are not actually emoji or part of the Unicode standard. Implementation, support, and blame lies entirely with the third parties involved.
