Hi Nasser, > upquote works. It fixes ' in verbatim. _but_ when adding > the --lua option, it no longer works. something breaks.
it seems that upquote loads different fonts with LuaTeX, it requires the textcomp package. The tex4ht configuration contained wrong character for \textquotesingle, it is the right single quote instead of apostrophe. I've fixed the sources. You can try the attached file lm-ts1.htf. Best, Michal
