Q. P is a common character across languages. But Q is mostly unused, at least outside the romance languages who appear to spell K that way. But that can be solved by letting the characters have the same code point, and rendering it as K in most regions, and Q in France. I can’t imagine any problems arising from that. :)
No, I’m pretty sure the weird o with the leg is in basic ASCII. It’s also missing Latin characters like Æ. It’s a very weird standard.
