Using an external library whose notion of string comparison and
letter-case cannot be controlled by Emacs is a non-starter.  With the
current machinery, a Lisp program or a user can control up/down-casing
by specifying a buffer-local case-table, and we won't give up this
important functionality.  Other than that, I'm not aware of anything
that libunistring can do that Emacs cannot: we import the same Unicode
tables as libunistring does, so we have the same data to do these
