Consider the following LaTeX file q.tex:

[
\documentclass{article}
\usepackage{fontspec}
\setmainfont{CMU Serif}
\usepackage[russian,american]{babel}

\begin{document}
\foreignlanguage{russian}{А}.
\end{document}
]

The letter А is a cyrillic one, U+0410. Running xelatex on it results in the message

xdvipdfmx:fatal: This font using the "seac" command for accented characters...

[Mark McGregor]

A more minimal non-working example:

[
\documentclass{article}
\usepackage{fontspec}

\setmainfont{CMU Serif}
%\setmainfont{cmunrm.otf}

\begin{document}
А
\end{document}
]

If you comment the first \setmainfont line and uncomment the second one, the file compiles. Rerunning /usr/bin/texlive-enable-fontconfig doesn't help.

I found an answer at the following:

 
http://tex.stackexchange.com/questions/296308/xelatex-setmainfontcmu-serif-produces-wrong-characters

Based on that, you can work around the problem by commenting out the 
type1 fonts in /usr/share/fontconfig/conf.avail/09-texlive.conf, like this:

$ cat /usr/share/fontconfig/conf.avail/09-texlive.conf
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
   <dir>/usr/share/texmf-dist/fonts/opentype</dir>
   <dir>/usr/share/texmf-dist/fonts/truetype</dir>
   <!-- <dir>/usr/share/texmf-dist/fonts/type1</dir> -->
</fontconfig>

Then rerun the command '/usr/libexec/fc-cache-1 -sv' from 
/etc/postinstall/zp_fontconfig_cache_1.sh.

What puzzles me is that the link above says that the problem is caused 
by bugs in xdvipdfmx that have been fixed in TeX Live 2016.  I'll look 
into this and try to find out why it still seems to be broken.

Thank you! The workaround seems to work.

Would this solution affect the compilation processes of lualatex (which does compile the file in question) or pdflatex?

No.  lualatex and pdftex don't use fontconfig.

By the way, I've filed a bug report about this problem:

   https://sourceforge.net/p/xetex/bugs/131/

Ken, thank you!

dying? The last bugfix was in March, months ago, and apart from A.R. 
nobody seems to work on it anyway...)

No, I don't think XeTeX is dying.  A look at its git repository shows 
lots of commits from Jonathan Kew and Arthur Reutenauer in the last few 
months.

The last commit was over 1 month ago: a 1-line change from JK. I'm not overly optimistic that anything will happen to this bug report at all. But, anyway, thank you for having reported!

Mark.

I had some private correspondence with Akira Kakuto about my bug report, 
and he said it isn't a bug.  The problem is simply that xetex has very 
limited support for type1 fonts, and the solution is to remove them from 
the fonts that fontconfig knows about, as you've done.  So I'll probably 
make this change the next time I update texlive.

[Mark]

Dear Ken:

Thanks for the notice!

Btw., recently I experienced xpdf failing to start due to rebasement 
errors similar to what a few people reported here months ago, and the 
xpdf version from your repository worked for me. So I'd be happy to see 
your xpdf compilation in the standard cygwin distribution.

Best,

Mark
