Re: [ft] [EXTERNAL] RE: get all glyphs

Hi Thomas,

have you tried to iterate over every charmap, as Laco suggested?  Basically
keeping your loop but putting something like that around it:

```
for ( int c = 0, cc = face->num_charmaps; c < cc; ++c ) {
  FT_Error  err = FT_Set_Charmap( face, face->charmaps[c] );
  if ( !err ) {
    // ... your loop from below ...
  }
}
'''

Also mind Laco's note about `FT_Load_Glyph';  you don't want to load
anything if you don't have to.

Best
Armin
