Revise Markdown handling of character entities. Ideally I'd like the ABC character entities to survive Markdown and then get converted. But because they start with '\', they don't. So I have no alternative but to convert them to HTML entities, which Markdown then converts to UTF-8.

\section{@SECTIONNAME@ tunes}

{\renewcommand{\arraystretch}{2.5}
\setlength\LTleft{0pt}
\setlength\LTright{\fill}
\begin{longtable}{@{}>{\raggedright\arraybackslash}m{0.2\textwidth}r@{}}
\input{@SECTION@-firstlines.tex}
\end{longtable}
}
