Btw, an alternative idea which might be worth exploring is to use
string-collate-equalp for comparison during search, or wcscoll it
calls on the C level.  That will use the character databases of the
underlying libraries, instead of using the Emacs's own databases (and
so will be less prone to customization), but that might be good enough
in this case.
