Workaround is never to use the cprotect package in tex4ht.

Hi Nasser,

I don't think you need to use the \cprotect command. It just seems that \left and \right commands cause issues when used in sections in the mathjax mode. We need to disable them. I've already fixed the sources and posted a workaround on TeX.sx.

Best,
Michal

I use cprotect package so I can use math in section titles. It works OK in pdf, but tex4ht generates strange characters at end of section title.

If I do not use cprotect, then it will not compile in tex4ht.

Is there a way around this? MWE

-----------------
\documentclass[12pt,notitlepage]{book}
\usepackage{cprotect}
\usepackage{amsmath}
\begin{document}
\title{my book}
\chapter{Listing of integrals}
\cprotect\section{\quad $\int e^x \left(1-x^3+x^4-x^5+x^6\right) \, dx$}

stuff

\cprotect\section{\quad $\int \frac{e^{\frac{x}{2+x^2}} \left(2-x^2\right)}{2 x+x^3} \, dx$}
text
\end{document}
-------------------------

Compiled using

make4ht -ulm default t.tex "htm,3,mathjax,notoc*,p-width"

gives ^^E^^L at end of title.

If I do not use \cprotect then it gives compile error.

Using TL 2019.

Thanks
