two letters upon another for math symbols

[xlstatik]

How is it possible to get two letters at the same place?
I have to create math symbols with a dot or a dash on top of a letter.
I know I can get these symbols whith shapes, but that is cumbersomely.
I am looking for some deadkeys or a vba-macro.

Also look at the equation editor

xbar is Alt-0214 in the Math Ext font from

xbar is Alt-0120 in the MS Reference 1 font.
