Fsvo "typically". On Emacs, and in Windows filenames [fortuitously, they
match in this case. Unfortunately, I don't believe there's an easy way
to get at the table used in Windows], upcasing is done on a
character-by-character basis, and AIUI neither of them do this, so
(string= (upcase "Straße") "STRAßE").
