Well, the obvious questions first.

[1] LANG=ru_RU.KOI8-R; export LANG

although I'm not 100% sure of this. (I'm a LANG=C person, if that. :-) )

[2] Does XSupportsLocale() return False? (Probably not,
since you're getting a copy of the string back. Might
be useful to just check, though.)

[3] The Xutf8TextPropertyToTextList() takes as its 4th parameter
an XICCEncodingStyle, which can be one of the following:

XStringStyle: either STRING or COMPOUND_TEXT items are returned.
XUTF8StringStyle: UTF8_STRING items are returned. (This is
an XFree86 extension; check for the macro X_HAVE_UTF8_STRING.)
XTextStyle: The encoding is the current locale. This is probably
what you want.
XStdICCTextStyle: STRING if the text is fully convertible to STRING,
otherwise COMPOUND_TEXT. (My manpage isn't all that clear
on why this is different from XStringStyle, and I've not tried
this stuff myself.)

My locale is OK, the problem exactly not here

SupportsLocale() return True

No Xutf8TextPropertyToTextList() but Xutf8TextListToTextProperty() takes
XICCEncodingStyle. Any way, I've examined all variants of
ICCEncodingStyle, but nothing changes (I can convert utf8 in
COMPOUND_TEXT only)

Properties are encoded as COMPOUND_TEXT, not UTF8. Your value would
lack the escape sequence (\033%G) to flag it as such, so it would be
treated as being in your current locale.

Yup.

Set the property with the output of Xutf8TextListToTextProperty.

The rationale for properties is to try to keep them as close to the
national language as possible (for compatablility with old programs
which have not been internationalized). Thus, if your UTF8 data is
expressible in KOI8-r (and that is the current locale), it will be
stored as such. Minimal escapes to UTF8 will be made for characters
that cannot be represented in the current locale.
