Thanks a lot for stepping forward!

Yes, the Unicode Annex #9 (UAX#9, for short), is a good place to
start.  You can find the latest version on the Unicode Web site.

You could also consider reading the archives of this list, where you
should be able to pick up some Emacs-specific aspects that you won't
find in UAX#9.

While you are chewing this up, I'll try to come up with something you
could do during the few weeks you have.  Do you have any preferences
as to what part(s) of the Emacs internals you'd like to deal with?
