@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.

FcBlanks is deprecated, <parameter>blanks</parameter> is ignored and

<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.

@DESC@
Constructs patterns found in 'file'.
If id is -1, then all patterns found in 'file' are added to 'set'.
Otherwise, this function works exactly like FcFreeTypeQuery().
The number of faces in 'file' is returned in 'count'.
The number of patterns added to 'set' is returned.
