This seems to work. Looks like I lied. What they do is drawing all combined runes on top of each other, first with fg, bg and others with fg, Color_none. They also replace combined rune pair with one rune from PRIVATE_USE when writing text to a terminal and then expanding it elsewhere, but that's irrelevant. So, the only solution I see here is write a specific function for drawing one combined character sequence and always break normal drawing on them. May be slow, but at least it will work. Fuck you, Xft.
