I guess the typical case would be when a user inputs a file name in
lowercase, een if the actual filename is mixed or upper case?

Hmm, not exactly. Presumably the case-insensitiveness in Windows only
handles single-character uppercase/lowercase pairs. A quick
experimentation shows that it is possible to have two files in the
same folder that differ in name only in that where the other has a
sharp-s, the other has "ss". These names would g_utf8_casefold() to
the same, yes?

I guess I'll have to experiment with all the entries in the
casefold_table in gunichartables.h to see if the same goes for all the
cases.

Exact documentation from Microsoft? Dream on...
