Use FT_Select_Charmap(face, FT_ENCODING_UNICODE) to select a Unicode
cmap, then loop over all input character codes with
FT_Get_First_Char() and FT_Get_Next_Char().  Those two functions
return the glyph index also.

Duplicates?  I don't understand.

The very problem is that a CIDfont resource is useless without a
proper CMap resource.  FreeType doesn't (yet) support CMap resources
-- does FontConfig do that?
