Dear Maintainers,
I am using font-latex-fontify-script set to invisible in order to hide _
and ^ in math expressions. Unfortunately, AucTeX fails to correctly
parse the file if there are underscores in the document outside of math
mode (for example, in labels or comments). Here are two examples:
\documentclass{article}
\begin{document}
\begin{equation}
\label{eq_1}
x_0 \end{equation}
\end{document}
\documentclass{article}
\begin{document}
\begin{equation}
% y_0
x_0 \end{equation}
\end{document}
For me, AucTeX displays the underscore in x_0 despite the
font-latex-fontify-script option. The second one is more problematic
because it is quite common to comment out LaTeX code with a lot of
subscripts and superscripts. This also leads to inconsistent
fontification in large files.
Thank you for maintaining AucTeX.
Best wishes,
Todor
