(sorry, fell asleep last night)

You mean: how do those things get into Emacs?

For this, I did a trick I like to do when I barely know what I'm
doing.

 - first, find an Unicode codepoint name which is somewhat
   distinctive (meaning: a string not likely to appear
   "spontaneously" out there by some strange genetic coincidence).
   I went with "REVERSED QUESTION MARK".

 - grep the Emacs sources for it (M-x grep find is my friend.
   It wants to be yours ;-)
   You do have the Emacs sources around, don't you?

And here it is:

  admin/unidata/UnicodeData.txt

There is a README file in that directory explaining where (and when)
all those files come from.

Or is it something else you are after?

Cheers
