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?

I hadn't rebooted my system for a long time and I just did. The issue is
gone and the man pages are displayed properly when  loaded with
configurations. I do not know why such difference.

I appreciate for taking time and effort in fixing this.
