OverStrike control character

Basically, yes. unicode has plenty of basic geometric shapes throughout that can be utilized to build interchangeable (and non-PUA) characters. (if Classical Yi ever get accepted, then youll be able to use just about any shape out there for your overstriking needs (the proposal lists over 88k new chars!))

> It seems the only serious use case for this character (as opposed to "it would be fun" or "it would be possible" or "Unicode has lots of empty code points, and look at the stuff they've already encoded") is that people could make up their own characters — so long as they consisted of two or more existing glyphs, one overstruck on the other — and they would have a non-PUA Unicode representation. Is that about the size of it?
