When my document has a figure with a label{aa--bb} or any other label that uses two hyphens (-) in a row (--), tex4ht produces a corrupt .odt file. Is there a way to fix this bug?

MWE

Using the same same setup as I did in an earlier question, concatenate head.tex, main.tex, and tail.tex then compile it using the command given by Michal Hoftich (@michal.h21) in his answer to that question.

main.tex:

%!TEX TS-program = xelatex

%!TEX encoding = UTF-8 Unicode



documentclass[12pt]{memoir}

usepackage{ifmtarg}

usepackage{calc}



%Greek

newcommand{greek}[1]{#1}

newcommand{gk}[1]{#1}



%Arabic

newcommand{ar}[1]{#1}

newenvironment{arab}{}{}

usepackage[american]{babel} 

usepackage{csquotes}

        cmsdate=        both, % reprints: print `origdate` as well as `year`

        compresspages=  true,

begin{document}



%%%%%%%%%%%%%%%%%%%%

%%%    My text goes here:    %%%%%%%%%%%%%%%%%%%%%%

Fig.~ref{aa--bb}.



begin{figure}[p]

begin{center}

label{aa--bb}

end{center}

end{figure}



%%%%%%%%%%%%%%%%%%%%

%%%    My text ends here:    %%%%%%%%%%%%%%%%%%%%%%

end{document}

In the directory, I then include myconfig.cfg (again from Michal Hoftich, for the purposes of making Arabic text appear properly):

Preamble{xhtml}

xeuniuseblock{Greek}

xeuniuseblock{Arabic}

makeatletter

ConfigureEnv{arab}{@rltrue}{@rlfalse}{}{}

makeatother

begin{document}

EndPreamble 

Then I run the command:

make4ht -ux -f odt  -c myconfig.cfg main.out.tex
