In fact, the initial problem was not with the messages. Please, see the end of this thread:
http://forum.texmacs.cn/t/hyphenation-doesnt-work-with-russian-language-only/384/32

If I open a new document, set the document language as Russian, and try to type almost any formula like:

<\equation*>
<gamma><frak-A><sqrt|>
</equation*>

then instead of the correct formula, I see something like in the attached png file. If set Roman then everything is correct. That is why I always manually set the Roman font for all my documents in Russian. I suggest making it a default behavior for Russian documents.

Pavel, could you please give more details on what I should do in order to reproduce it.  When I select 'Russian' in the focus bar, I don't see any of these messages anymore.

The problem is still here in the newest version 2.1.

I suppose that all this strange behavior is related to the special support of Cyrillic languages in TeXmacs and some internal conversions related to that. Maybe it is better to turn this support off by default and treat Russian as any other language like French or Spanish? If I change from the focus bar the font from Cyrillic to Roman, then everything is fine!  Nowadays almost everyone uses Unicode to write papers. I’m not sure whether this special support for Cyrillic languages is very relevant now.

Many thanks, Joris.

The errors `missing 'rm-cyrillic' master` are now gone.

When entering math symbols I still get missing characters in the equation and the error

missing 'rm-mathsymbols' master

appears on the command line.

I think that I fixed the problem in revision 13533.
The cyrillic computer modern font is fairly fragile.
Please keep on testing.

The error message disappear if I change the line 158 in `src/Graphics/Fonts/font_translate.cpp`

t ("cyrillic")= "roman";

to for example

t ("cyrillic")= "Stix";

As reported on the forum:
forum.texmacs.cn/t/beamer-with-overlays/461/

When Russian or Ukrainian language is selected, several math fonts are missing. On the terminal the error `missing 'rm-cyrillic' master` is shown.
