If you need it, we can add a function to access SFNT tables
within TrueType or OpenType. Something like:

   FT_Error   FT_Load_Sfnt_Table( FT_Face    face,
                                  Sfnt_Tag   tag,
                                  FT_Byte*   buffer,
                                  FT_ULong   buffer_size,
                                  FT_ULong  *table_size );

Another solution would be to implement the relevant functionality
in a new function. What about:

  FT_Error   FT_Map_Char_Codes( FT_Face     face,
                                FT_ULong    code,    // first charcode
                                FT_UInt     count,   // number of codes/glyphs
                                FT_UInt*    glyphs,  // output glyph index 
buffer
                                FT_UInt     flags )

#define  FT_MAP_CHARS_DEFAULT         0                                   
#define  FT_MAP_CHARS_IGNORE_BLANKS   1  // "spaces" return glyph index 0
#define  FT_MAP_CHARS_IGNORE_CHARMAP  2  // assume input is glyph index range
.... maybe other interesting flags .....

the last solution has the advantage of not being format specific..

What would you prefer ??
