@PURPOSE@ map Unicode to glyph id
@DESC@
Maps a Unicode char to a glyph index. This function uses information from
several possible underlying encoding tables to work around broken fonts.
As a result, this function isn't designed to be used in performance
sensitive areas; results from this function are intended to be cached by
higher level functions.

@TYPE1@ FT_Face% @ARG1@ face

@PURPOSE@ compute unicode coverage
@DESC@
Scans a FreeType face and returns the set of encoded Unicode chars. This scans
several encoding tables to build as complete a list as possible.
If 'blanks' is not 0, the glyphs in the font are examined and any blank glyphs
not in 'blanks' are not placed in the returned FcCharSet.

@PURPOSE@ compute unicode coverage and spacing type
@DESC@
Scans a FreeType face and returns the set of encoded Unicode chars.
This scans
several encoding tables to build as complete a list as possible.
If 'blanks' is not 0, the glyphs in the font are examined and any blank glyphs
not in 'blanks' are not placed in the returned FcCharSet.
<parameter>spacing</parameter> receives the computed spacing type of the
font, one of FC_MONO for a font where all glyphs have the same width,
FC_DUAL, where the font has glyphs in precisely two widths, one twice as
wide as the other, or FC_PROPORTIONAL where the font has glyphs of many
widths.
