Follow-up Comment #3, bug #236 (project tex4ht):

I installed the new htf files in TL. There were a ton. Hope that was the right
thing to do.

Follow-up 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.

Hi Wojtek,

nice to hear from you :) I understand it now, it is "rohaté o" in
Czech. I've found that it uses private unicode area in Latin Modern
fonts. It probably doesn't have standard Unicode mapping.

Here: https://en.wikipedia.org/wiki/%C3%98_(disambiguation) I found
some alternatives, in particular:

https://en.wikipedia.org/wiki/Voiceless_bilabial_fricative
https://en.wikipedia.org/wiki/Phi

But maybe it is best to just use "o" and "O"? Is this letter used much?

Best regards from cloudy and warm Prague :)

Orogate (also orogate) is taken from polish rogate o (which means letter o
with horns).

Still do not known if the letter has unicode equivalent, but probably can
(or can not) be found in TeX-Gyre fonts:

Follow-up Comment #1, bug #236 (project tex4ht):

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.

 Summary: using {newtxtext,newtxmath} packages breaks MathML
generation in tex4ht

Details:

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.
