Derivatives of overscript variables

Question

If we have an expression with terms of some variable and terms of the same variable with some overscript, the differentiation of this expression does not entirely function.

The problem is that Mathematica does not recognize $\stackrel{\text{batman}}{x}$ and $x$ as two intrinsically different variables. Anyone know of some fix to this?

Try the notation package and the Symbolize command. (but what you are trying to do is very confusing. Why not use normal symbols?) — Nasser, Dec 30 '14 at 16:37
Thanks for the tip on Notation package and Symbolize command, worked like a charm. — user23366, Jan 01 '15 at 03:02

A simple approach is to have a separate variable format as Overscript[x, batman]

Format[xbat] := Overscript[x, batman];

expr = xbat^2 + x^2

enter image description here

D[expr, xbat]

enter image description here

D[expr, x]

2 x
