• - Unicode codepoint lookup/search tool

Notice: I'll be updating the information in the next weeks. It'll be broken occasionally.

Input may be:

U+0420, U+205AC - codepoint
0420, c3a9, E2808B - codepoint as hex. (When hex is decodable as UTF8, such as c3a9 for U+E9, we add such a link)
➨, ➨ - numeric HTML entities
String with any characters, e.g. ㋛ ☺ ㋡ or (ノಠ益ಠ)ノ彡┻━┻ . Will link to constituent characters
(used when input isn't recognised as one of the above)
Name search such as cyrillic de, n, numeral, plus-minus sign, exclamation question, arrow right, hieroglyph. (Includes entity names like middot and Ntilde, from HTML and others).

Input
Type here
Input was:	`U+2022`
	...interpreting as U+00 style format (hex codepoint, two to eight digits)
Character:	• (U+2022)

Some unicode data
Character name	BULLET
Categories	Other Neutrals, punctuation:Other
Links elsewhere:	fileformat.info/info/unicode/char/2022 codepoints.net/U+2022
Unicode block	General Punctuation, U+2000 to U+206F (see also the according PDF on unicode.org)
Normalization	No normalisations change the data (does not necessarily mean nothing decomposes to this form)

Font info (experiment)

Encoding
Character stuff
Named entity	HTML 2: not defined HTML 3.2: not defined HTML 4 and XHTML 1.0: • XML 1.0: not defined
Alt code	Alt 7 Alt 0149 Alt 149 (where cp1252-based, not a given)
String stuff
HTML/XML numeric entities	All but basic alphanumeric encoded (hexadecimal and decimal): • •
UTF8 bytestring	as hex: e280a2 (UTF8 bytestring length is 3)
URL-encoded UTF8	%E2%80%A2
Python string before py3k	Unicode string: u'\u2022' UTF8 bytestring: '\xe2\x80\xa2'
...in py3k	Unicode string: '\u2022' UTF8 bytestring: b'\xe2\x80\xa2'
Javascript (≥1.3)	"\u2022"
LaTeX (incomplete experiment)	Character in LaTeX: \textbullet

Layout

Note that of the ~1.1 million codepoints under U+10FFFF (the current cap), ~900K are unused, ~130K are private use, and only ~100K are general-purpose graphic codepoints (about half in BMP).
Grouping used below is somewhat arbitrary, but looks halfway sensible
For more on planes, see http://en.wikipedia.org/wiki/Mapping_of_Unicode_characters#Planes

Mouseover shows a range's codepoint range, links are to unicode.org PDFs.
Nameless gray blocks are reserved, unused or restricted areas, and show their size.
If we are showing a single codepoint above, the range it is in is bolded below.
