There seems a problem using \sum with tex4ht. I was able to
reproduce it all the time with specific configuration. This
happened when I was trying different configurations to check
some things.
Here is MWE:
----------------------------
\documentclass{article}
\begin{document}
$\sum F_{x}=m\ddot{x}$
\end{document}
-----------------------
Here is the command to produce the error
make4ht foo.tex "nma"
here is the error
--------------------------------------
(/usr/local/texlive/2013/texmf-dist/tex/generic/tex4ht/html-mml.4ht)
(/usr/local/texlive/2013/texmf-dist/tex/generic/tex4ht/html4-uni.4ht))
(./foo.aux))
! Bad mathchar (79119).

l.6 $\sum F_
{x}=m\ddot{x}$
?
--------------------------------
Here is nma.cfg which is in the same folder as foo.tex
---------------------------------
\Preamble{xhtml,mathml,ext=htm,charset="utf-8",p-width,pic-align}
\begin{document}
\Configure{$}{\PicMath}{\EndPicMath}{}
\Configure{PicMath}{}{}{}{ class="math" align="absmiddle"}
\EndPreamble
-----------------------------------
If mathml is removed from the above, then no error.
If mathml is now back to the .cfg, but removing the first \Configure
line inside the \begin{document} then the error goes away as well.
Only when mathml and the \Configure{$}{\PicMath}{\EndPicMath}{} is
there, will this error show up.
Using texlive 2013, on linux.
Can someone please verify this and if you think this is a bug and if
I should enter a bug report then.
thanks,
