Yes, that's expected for `enable-multibyte-characters'. (Though I
don't know how it is implemented, not having read the code.) You can
toggle a buffer between multibyte and unibyte with the command
`M-x toggle-enable-multibyte-characters'. But I believe that this
should normally not be necessary. Emacs uses multibyte buffers by
default. Do you start it with the "--unibyte" command line option? Or
do you have `(standard-display-european t)' somewhere in you .emacs?

Toggling with `toggle-e-m-characters' when Gnus displays the article
won't help, because the strange characters and numbers that you see
are probably the UTF-8 representation interpreted as unibyte
characters. So the article was not decoded in the first
place. Toggling multibyte will only help, if the UTF-8 got decoded to
Emacs' internal multibyte representation (emacs-mule). 

But I think that all this will just work, if you find out what causes
your Emacs to use a unibyte buffer.
