This would be great. I need a way to cleanly document code implementing equations that contain letters in the superscripts and subscripts. x_i^j, for example, might be the position of Body i in Frame of Reference j. I can mentally pack it back together when it's just the one, but it would be nice if it could more closely resemble the original equation.
Alas, I was told that was "exactly what Unicode doesn't want to endorse."
