Then I get confused! I made three example (German, French and Russian)
with the same font, small example I already shown.

Now I run them through xetex (with slight changes in files because of
luaotfload use). All works fine (with plain xetex). So I miss something:
why the same file with Russian works with xetex while with luatex
doesn't? I'm asking because want to fix that situation.

Example for xetex
%\input luaotfload.sty

%\font\test={file:cmunrm.otf} at 12 pt
\font\test=[cmunrm.otf] at 12 pt
\uselanguage{ngerman} %%% also: french and russian
\input sample_de.txt %%% also: sample_fr.txt and sample_ru.txt

(As you anyone can see I don't use any packages).

P.S. Both xetex and luatex gives bad hyphenation at the same words at
the same points on my test file. I think this is good indication.
