Yeah ok. the parsing itself tries to use the allegro unicode api to find the
right char, and shouldn't mangle anything so long as allegro doesn't. But then
it has to know what format the incoming string is, so it can create the right
type when parsing and spiting in the path api.
Of course, those al_path_ functions that directly call fshook api functions
might want to detect the proper system encoding.. Or the path api ONLY deals
with os native fs encoding.. I dunno. I'm tired.
