+% \subsection{Further processing of Unicode converted files}
+% \label{sec:further-processing-utf-files}
+% Unicode files can be further processed by document converters such
+% as John McFarlane's |pandoc|\footnote{\url{http://pandoc.org/}}. To
+% take here one example, here is how |file_out.tex| can be converted
+% from \hologo{LuaLaTeX} into Open Document format (|.odt|):---%
+% \iffalse
+%<*example>
+% \fi
+\begin{arabluaverbatim}
+  pandoc -s file_out.tex -o file_out.odt
+\end{arabluaverbatim}
+% \iffalse
+%</example>
+% \fi
+% 
+% However, specific commands such as \cs{txarb} or \cs{txtrans}, which
+% are not known to |pandoc|, must be redefined explicitly in the
+% preamble to prevent the converter from gobbling their arguments,
+% like so:---%
+% \iffalse
+%<*example>
+% \fi
+\begin{arabluaverbatim}
+  % preamble (below the line that loads arabluatex)
+  \usepackage{suffix}
