Up to date to Unicode 12.
New version, public in early stages. As I work on it, it will be missing features, occasionally its data, and sometimes give errors.
Input currently recognised:
- String with any characters, e.g. ㋛ ☺ ㋡ or € or (ノಠ益ಠ)ノ彡┻━┻ or ᘛ⁐̤ᕐᐷ or ༼ つ ◕_◕ ༽つ or ♥︎ ♥️.
- Refereces to one or more codepoints (one style at a time)
- U+205AC, U+1F9C0, U+2764
- 0420, c3a9, e2808b - hex that is codepoint and/or UTF8 (e.g. e2808b is probably U+200B, c3a9 could be either U+E9 or U+C3A9)
- %C3%A9 - percent-encoded hex UTF8 (probably from URLs)
- \xd0\xa0, \uc3a9, \u{c3a9}, \ud83e\uddc0, \U0001F9C0 - some escape styles used in code
- ➨, ➨, · decimal/hex/named HTML/XML entity
- Name search such as cyrillic de, n, numeral, plus-minus sign, exclamation question, arrow right, hieroglyph. Includes entity names like middot and Ntilde, and some of my own fuzziness, also to help find confusables.
Or you could get random character.

PUA-A - Private Use Area A:
PUA-B - Private Use Area B:
Note that of the ~1.1 million codepoints under U+10FFFF (the current cap), only ~140K are general-purpose graphic codepoints (about half in BMP), ~130K are private use (with no defined characters), and ~830K are unused.
The grouping used above is somewhat arbitrary, but looks halfway sensible
