Having such an option seems like a good idea. I'm not sure about all of the
flags, the first one seems to contradict the rest. Could you send me one of
those fonts ?
I've also stumbled upon a font with seemingly wrong kerning information. It's
the one in attachment, the kerning between "N" and "o" in it is a rather
large number. Maybe I am missing something ? ftstring displays it correctly
only when kerning is turned off.
If that is really the case, we might want yet another option to disable
