I guess you refer to `mm-coding-system-priorities', aren't you?

It might also be an Emacs configuration issue.  `C-u C-x =' will tell
you which font is used for -1 / and -15.  I'd suggest to load a file
with Scandinavian chars with "emacs -q -no-site-file" with both
charsets (`C-x C-m c iso-8859-... RET C-x C-f foo.txt RET').  Maybe
there's some error in your configuration.

Well, Emacs can do something: `unify-8859-on-decoding-mode', but it
has some pitfalls.  If your Gnus is sufficiently recent, you might use
`mm-charset-override-alist'.  But I wouldn't recommend this unless
when using some old/non-MULE (X)Emacs which is not aware of Latin-9
(even then, `mm-charset-synonym-alist' would make more sense.)

Latin-1 and Latin-9 differ in 8 positions[1], not only the EUR char.

Bye, Reiner.
