Hi Ulrike, thanks for the report. The problem here is that TeX4ht writes all section titles to the .4tc file. It uses \protected@edef internally, which fails with \footnotemark.

\footnotemark is redefined by TeX4ht, using \HLet. The resulting command is not robust, but we can make it robust using \MakeRobust. Is that a safe solution?

The following document works fine with pdflatex but errors with make4ht:

~~~~
\documentclass{article}
\begin{document}
\section*{abc\footnotemark}
\end{document}
~~~~

~~~~
! Use of \o:@xfootnotemark: doesn't match its definition.
\@ifnextchar ...eserved@d =#1\def \reserved@a {#2}
\def \reserved@b {#3}\futu...
l.178 \section*{abc\footnotemark}
~~~~

(Note that this uses a starred section, with an unstarred \section it would error in pdflatex too).
