Regular expression matching emoji in Mac OS X / iOS
Note: this question could look odd on systems not supporting the included emoji.
This is a follow-up question to How do I remove emoji from string.
I want to build a regular expression that matches all emoji that can be entered in Mac OS X / iOS.
The obvious Unicode blocks cover most, but not all of these emoji:
- U+1F300..U+1F5FF Miscellaneous Symbols And Pictographs
- U+1F600..U+1F64F Emoticons
- U+1F650..U+1F67F Ornamental Dingbats
- U+1F680..U+1F6FF Transport and Map Symbols
Wikipedia provides a compiled list of all the symbols available in Apple Color Emoji on OS X Mountain Lion and iOS 6, which looks like a good starting point: (slightly updated)

emoji = people + nature + objects + places + symbols # all emoji combined
Most characters have a single code point and converting these would be easy:
- ๐ U+1F600 (Grinning Face)
But some characters are "encoded using two Unicode values":
- โบ๏ธ U+263A U+FE0F (White Smiling Face, Variation Selector 16)
- ๐ฏ๐ต U+1F1EF U+1F1F5 (Regional Indicator Symbol Letter J / Regional Indicator Symbol Letter P)
- โฌ๏ธ U+2B1B U+FE0F (Black Large Square / Variation Selector 16)
And some even have 3 codepoints:
๏ธโฃ U+0023 U+FE0F U+20E3 (Number Sign / Variation Selector 16 / Combining Enclosing Keycap)
(Variation Selector 16 means "emoji style")
How can I split this list into characters (without splitting combined characters), find their code point(s) and finally build a regular expression matching them?
The regex doesn't have to respect "missing" characters within larger blocks, i.e. it's okay if the 4 Unicode blocks mentioned above are entirely covered.
(I'm going to answer this myself if I don't get any answers, but maybe there's an easy solution)

This regex matches all 845 emoji, taken from Emoji unicode characters for use on the web:

Examples can be found here: https://stackoverflow.com/a/29115920/1911674
EDIT: I udpated the regex to exclude ASCII numbers and symbols. See comments from How do I remove emoji from string for details.

The upcoming Unicode Emoji data files would help with this. At the moment these are still drafts, but they might still help you out.
By parsing http://www.unicode.org/Public/emoji/1.0/emoji-data.txt you could get quite easily get a list of all emoji in the Unicode standard. (Note that some of these emoji consist of multiple code points.) Once you have such a list, itโs trivial to turn it into a regular expression.
Hereโs a JavaScript version: https://github.com/mathiasbynens/emoji-regex/blob/master/index.js And hereโs the script that generates it based on the data from emoji-data.txt: https://github.com/mathiasbynens/emoji-regex/blob/master/scripts/generate-regex.js
