# Fixed width font in Latex

I can't figure out how to have every character have the same fixed width in Latex. In this example:

I would like the characters

{i \in \math

to have the same width as the others.

From the manual page (auctex) Fontification of math:

In order to make math constructs more readable, font-latex displays subscript and superscript parts in a smaller font and raised or lowered respectively. This fontification feature can be controlled with the variables 'font-latex-fontify-script' and 'font-latex-script-display'.

You can turn this off by customizing the variablefont-latex-fontify-script to nil.
