-  It is recommended that an application use the GetFontLanguageInfo function
-  to determine whether the GCP_DIACRITIC, GCP_DBCS, GCP_USEKERNING, GCP_LIGATE,
-  GCP_REORDER, GCP_GLYPHSHAPE, and GCP_KASHIDA values are valid for the
-  currently selected font. If not valid, GetCharacterPlacement ignores the
-  value.
-
-  M$ must use a preset "compiled in" support for each language based releases.
-  ReactOS uses FreeType, this will need to be supported. ATM this is hard coded
-  for GCPCLASS_LATIN!
