alt Hacker NewsI don't understand. No matter what fancy things you do with superscripts and subscripts, you're not going to be able to do even basic things you need for equations like use a fraction bar, or parentheses that grow in height to match the content inside them.
At a fundamental level, Unicode is for characters, not layout. Unicode may abuse the ZWJ for emoji, but it still ultimately results in a single emoji character, not a layout of characters. So I don't really understand what you're asking for.

Why not? Things like Arabic ligatures already do that, no?
Agreed. I think MathML is intended for layout of formulas and integrated into browsers nowdays, but I never used it, so don't know if essentials are missing?
