[tex4ht] Three questions about errors when using mk4ht to create MathJax compatible files

[Michal Hoftich]

Hello Steve,

your first problem may be caused by using `NoFonts`  option either on the
command line

    mk4ht xhmlatex $1 "ht5mathjax, NoFonts"

or in the config file

    \Preamble{xhtml,mathml, NoFonts}

This option prevents tex4ht from inserting formatting elements based on
font properties.
Problem with these elements is, when you use accented characters, like:

    \textit{nazdar světe}

sequence like

    <span class="x">nazdar sv</span><span class="x">ě</span><span
class="x">te</span>

is created. If you don't use accented characters, you probably don't need
NoFonts option.
If you really want to use this option, you must style font changing
commands yourself, like this config file:

   \Preamble{xhtml, mathml, NoFonts}
   ...
   \begin{document}

   \Configure{textit}{\ifvmode\ShowPar\fi\HCode{<em>}}{\HCode{</em>}}

   \renewcommand{\sectiontitle}[1]{\ifvmode \IgnorePar\fi%
   \EndP\HCode{<div class="sectiontitle">}#1\HCode{</div>}%
   \IgnoreIndent\par%
   }
   \Css{.sectiontitle{text-align:center;font-size:large;}}
   \EndPreamble

Regarding the other two problems, without some sample it is hard to tell
what's going on, compilation run without problems for me.

Regards,
Michal
