Because Microsoft uses an ugly hack: You have to add 0xF000 to the
character code if FT_ENCODING_MS_SYMBOLS is active.

You shouldn't do that in general.  Only the SFNT format has the
PID/EID pair to identify the encoding.  For other formats we have to
emulate it.  You should use FT_ENCODING_XXX where possible.  If this
really doesn't help look into `ttnameid.h'.
