So the question now becomes what do you have in your setup that causes
this.  I'm guessing you do something that changes the defaults for
encoding/decoding text.

What its suggests depend on your customizations.

The font has nothing to do with this.

They have been doing that since Emacs 20.1.  This is how you visit a
file whose encoding Emacs cannot guess correctly.  You just didn't
have the pleasure of bumping into this problem until now.

Another possibility is to visit the file normally, see that it wasn't
decoded correctly, then type "C-x RET r utf-8 RET", which will revisit
the file using the specified encoding.

It doesn't.  You have something in your customizations that runs afoul
of your expectations (which do work in "emacs -Q").
