Eh, I do still wish super/subscript characters in unicode were a bit more thorough. Several times a day I randomly remember the fact that every lowercase letter in the English alphabet except q has a unicode superscript character, and every single time it ruins my day.
My problem is still with the fonts- I can't find one that even has all of (i,j,k,x,y,m,n,p,q,r) as both super- and sub-scripts. I end up either using capitals or just sucking it up and writing X_i^r or something.
