That seems fine; you want Xft to use no charmap which this will do.

However, realize that I just fixed Xft to share faces and fonts so that 
multiple fonts referencing the same face will share the underlying 
FreeType data structures; if you open more than one font, you'll need to 
be careful to set the encoding and sizes with the (soon to be exported)

	Bool
	XftFreeTypeSetFace (FT_Face face, FT_F26Dot6 size, int charmap)

interface instead.  The 'charmap' is the index into the list of supported 
encodings for that face (face->charmaps[charmap]).  You can search that 
list to make sure an iso10646 encoding exists for your application.  This 
is independent of the charmap used by a particular font.

That won't work any longer...
