Sat Jul 25 14:18:19 2020, comment #2: In the end, I've identified all those glyphs, so Newtx fonts are now supported. The HTF files were generated automatically, so I hope that everything is correct.	Michal Hoftich <michal_h21>
Fri Jul 24 22:29:31 2020, comment #1: OK, I am working on this question for more than five year now. Some details can be found in my answer on TeX.sx: https://tex.stackexchange.com/a/460843/2891 Thanks to Michael Sharpe's talk at TUG, I learned about existence of the glyphtounicode-ntx.tex file. It contains mapping of glyphs from Newtx fonts to Unicode. I am now able to generate .htf files where only relatively small number of glyphs doesn't have the correct mapping to Unicode. Here is the list: aciiacutedbl asciiacute asciibreve asciicaron asciidieresis asciigrave asciigravedbl asciimacron circledP cwmascender cwmcapital guillbracketleft guillbracketright hyphendblchar newtieaccentcapital newtieaccentlowercase openbracketleft openbracketright orogate Orogate I found visual appearance of some of these in this file: http://texdoc.net/texmf-dist/doc/fonts/lm/lm-info.pdf Some of them, like cwmcapital clearly doesn't have any visual appearance. Others like orogate, are some esoteric characters, that I haven't ever seen. I do not know if they have any corresponding Unicode character. If anyone know about Unicode mapping for any of these, I will be more then happy to add them to the HTF files. I hope to add them to TeX4ht sources soon.	Michal Hoftich <michal_h21>
Tue Jan 6 19:51:32 2015, original submission: There is a work around for this, but adding it here for tracking just in case. I found when adding the line \usepackage{newtxtext,newtxmath} breaks mathml generated by tex4ht and hence the math looks bad when viewed in the browser. It seems to be a font issue. \documentclass[10pt,notitlepage]{article} \usepackage[T1]{fontenc} \usepackage{amsmath} \usepackage{newtxtext,newtxmath} \usepackage{etex} \begin{document} \[ \int \sin(x) \, dx \] \end{document} compiling as htlatex foo.tex "nma.cfg,charset=utf-8" " -cunihtf -utf8" Produces invalid HTML. Please see http://tex.stackexchange.com/questions/220555/why-using-newtxtext-newtxmath-packages-breaks-mathml-generation-in-tex4ht Work around is not to use \usepackage{newtxtext,newtxmath} when compiling with tex4ht if target is mathml.
