Comment:

 In [attachment:35293.4.diff]:

 - Expand the fallback regex in `wp_emoji_regex()`.
 - Add unit tests.
 - Improve inline docs.

 I tested optimising the regex that the Gruntfile task generates, but ran
 into a couple of problems - it didn't really save much space, and the code
 points still need to be unravelled for the `entities` regex, as that can't
 use character ranges for matching.
