|
|
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.

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.

FC_DUAL, where the font has glyphs in precisely two widths, one twice as
