It's very strange, because I cannot reproduce the problem on my
system, with UTF-8 encoded man pages, although my system's
locale-coding-system is also iso-latin-1.  When I override the default
encoding with "C-x RET c", the man pages are displayed correctly.

From the screenshot you sent, I see that it was taken not in "emacs -Q",
but on Reddit you said that "emacs -Q" shows the same problem?

Ok, I'll check it out.  Not sure where the problem is.

Great, thanks for telling us.  I'm therefore closing this bug.
