It may be useful to study how Unicode handle this problem, I believe
they have mechanisms to specify how to do up/down-case etc for
characters.  It is a fairly complex problem in general.

This reminds me, now that the Unicode tables have been released under
a free license, would it make sense to extend C-x = (or probably
rather C-u C-x =) to display the Unicode database information for that
character?  I would find that useful in many situations.
