Gak, you're right. In file SpecialCasing-4.1.0.txt there
are half a dozen locale dependent casings. Seems like
the best way to handle this would be for the case mapping
functions to accept an extra parameter representing
the locale?

In Ocaml you could default this argument (can you do
that in MLton?)
