Is it possible to overlay a symbol with another?
I want to write an equal sign with a question mark overlayed (or the other way around).
Note I don't want
\stackrel{?}{=}
I want the question mark to be right on top, to cross over the equal sign (which creates kind of a new sign).
Is this possible? How? Or is there a one character sign for this?

You can overlay the symbols the following way: Box the wider one and let the other one lap over it (using
\rlap
or\llap
). The correct centering is achieved by placing the second character into a box with the equal width but using\hss
to center it. The correct size for the different math modes can be adjusted using\mathchoice
