I don't know enough about glyphs and characters. Can someone comfirm
the following? If the application calls EnumFontFamilyEx for the
current font of the hdc will the callback include enough information for
the application to do the character-to-glyph-index conversion itself? It
looks to me like it should. If that is the case then I understand what
is going on.
