Hi,
As explained the issue is now solved, except for "chancery". I lower to
minor for now. Please not that I had to change the command to "mk4ht
htlatex a.tex", else the compilation fails. As I don't understand
anything of tex4ht I can't tell if this is a new bug.

The following input:
\documentclass{article}
\usepackage{avant}
\usepackage[T1]{fontenc}
\begin{document}
first
\textsf{first}
\end{document}
with the following command:
mk4ht htlatex a.tex "html,uni-html4,css2,charset=utf-8,info" " -cunihtf
-utf8"
gets the following HTML output:
first
ørst
Notice how the fi (fi; U+FB01) ligature becomes ø (small o stroke; U+00F8).

We got the following two statements from upstream:
Michal Hoftich:
Thanks for the report. The 8-bit fonts can be sometimes a bit mess. Even
if a standard encoding is used, some characters, especially ligatures
can be non-standard, which results in such errors. tex4ht uses special
files with conversion tables between font characters and Unicode. These
tables were originally written by hand, so they may contain errors.
I've fixed the files using Htfgen [1], tool that can generate conversion
tables automatically. I've fixed lot of bugs and added new features to
this tool, so the updates for text fonts should be mostly automatic in
the future.
Math fonts are a different story, as they often contain unique glyphs
that are not even in Unicode.
Karl Berry:
I committed the new versions of the adobe htf files to TeX Live (r51905).
I also realized that a number of htf files were being generated in
tex4ht dev but weren't in TL yet, so I committed those too (r51906).
Finally, I noticed that three files in TL were no longer being generated
(as far as I could see), so I removed them:
unicode/ec/eccc.htf
unicode/pxfonts/pxbsyc.htf
unicode/txfonts/t1x.htf
(in texmf-dist/tex4ht/ht-fonts). Guess we'll see if that causes trouble.
More discrepancies remain between dev and tl, but we'll resolve those
another time. Closing this ...
Now your minimal example works and also the other font families you
mentioned later one, except "chancery". I guess I have to open another
bug w/ lower prio to have this part of the issue solved too.

The problem is with this line. It confuses TeX4HT in its attempt to
map TeX fonts to HTML fonts using the .htf files.
Without this, the conversion works correctly.
That was a minimal example: It also works correctly w/o the
\usepackage{avant} line as well.
So fontenc is fine with Computer Modern, but not Avant Garde.
These fonts work:
- computer modern (default)
- lmodern
- charter
- palatino
- times (both serif and sans-serif)
- utopia
These do not:
- avant
- bookman (both serif and sans-serif broken)
- chancery
- newcent (both serif and sans-serif)
