#include <fontconfig.h> #include <fcfreetype.h>

FT_UInt FcFreeTypeCharIndex (FT_Face face, FcChar32 ucs4);

     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.
