Then you shouldn't expect Emacs to guess UTF-8 encoding correctly in
every single instance.  Distinguishing between UTF-8 and Latin-1 is
generally impossible with the current state of the art of coded
character sets support in Emacs.  It might work in certain cases, but
that's sheer luck.

One way to work around that in your specific case, without changing
your global defaults, is to add a `coding:' cookie to your .gnus.el
file.
