Thanks.  This is very strange, since the Courier New font, which is
used for the default face in "emacs -Q" on Windows, does have that
character.  I tried on 2 different Windows systems, and on both Emacs
used Courier New.

Does anyone else see this?

Could you please do the following and post the results?

  emacs -Q
  M-: (setq font-log nil) RET
  C-x 8 RET 444 RET
  RET
  font-log C-j

The "font-log" part in the last line should be on a separate line in
the *scratch* buffer (that's what RET before it is meant to arrange),
and C-j (i.e. Ctrl-j) should be pressed with the cursor after the 'g'
character that ends "font-log".

The result of C-j will be a long list, with some "..." in it.  Please
go to each such "..." and press RET on it, to have the list fully
expanded.  Then post here that list.

Thanks.

Thanks.  This still has the ellipsis "..." at the end:

So please repeat the experiment, but this time go to the ellipsis and
press RET on it.  That should expand the list to make it longer;
please post the full result.

A year later, I bumped into a system where I saw something very
similar, so I debugged this.

Note that iso10646-1 charset never appears in the above log, although
the setup for Cyrillic in the default fontset is this:

     (cyrillic ,(font-spec :registry "iso10646-1" :script 'cyrillic)
	       (nil . "ISO8859-5")
	       (nil . "microsoft-cp1251")
	       (nil . "koi8-r"))

IOW, iso10646-1 is the first registry value Emacs should have tried,
but it is nowhere to be seen in the above log.

The reason for this is that the fontset is reordered according to the
locale's preferences, as recorded in Vcharset_ordered_list and
Vcharset_non_preferred_head, and these are screwed up because Windows
returns to us a bogus locale name "ZZZ".  That causes the iso10646-1
part of the Cyrillic fontset to be pushed way down the preference
order, and we begin by examining the other registry values.

Even so, iso8859-5 should have saved the day, but there's another
problem: we don't have information in w32-charset-info-alist for
mapping iso-8859-5 into Windows charset constants.

So I have now fixed both problems on the emacs-27 branch, and as
result the Cyrillic characters are displayed using Courier New, as
expected.

Do you still have access to that system where you saw the problem?  If
so, can you build Emacs from the recent emacs-27 branch and see if the
problem is solved?  Even if you cannot build Emacs, I can tell you how
to fix the problem manually.

Thanks.

Yes, this change will appear on master soon, and then will be merged
to the native-compile branch.

The telltale sign of the problem is that

  M-: (getenv "LANG") RET

produces a bogus "language" of "ZZZ".  You could try fixing the
problem manually even before the change gets to you with

  M-x set-locale-environment RET RUS RET

Did you have time to test this yet?  Thanks in advance.

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.

[Message part 1 (text/plain, inline)]

Sorry for delay - there was no changes after Eli's fixes, but luckily I found working solution:
 (set-language-environment "ASCII")
(set-coding-system-priority 'utf-8 'utf-16 'windows-1251)
These strings in config fixed the issue.
