I wonder whether FcFreeTypeCharSet is what you really want here.  It
uses a lot of heuristics which almost certainly won't match what
Windows does, so we're probably better off writing our own.  A test
(on say Arial) would be useful here.

Also note that even if you do use the Fc* functions you'll need to
check that the pFc* ptrs are non-NULL before calling them.

Huw.
