Sorry, but I have no clue here. I think it can simply take a char,
whatever its numerical value means (see below). I'd just make a
font_is_suitable helper that defines a char array and iterates through
it, checking pango_font_get_coverage foreach array member.

I'm really interested in the meaning of a character's integer value,
maybe you could explain this to us? :)
