Unicode defines normalizations for this.  You can convert Unicode strings
to "canonical forms" for comparisons.  There are several levels of canonical
forms, for example there's one that ignores case distinctions.  Unfortunately
doing this correctly requires the use of large tables, so we might be better
off linking to a unicode-support library.  There are a few out there.
libunicode, for example :-)
