To clarify what I meant: Emacs from CVS is the only variant I know of
that has support for [:upper:], [:lower:]. and [:alnum:] in regular
expression classes.  Emacs-wiki will use these instead of their near
equivalents "A-Z", "a-z", and "A-Za-z0-9" in its regular expressions
when you are using Emacs from CVS.  Otherwise, you'll have to do a bit
more work.  See the last paragraph of this message for details.

That's funny; I'm not entirely sure what the problem could be.  It
should work properly as long as you are using the latest development
tarball (http://www.mwolson.org/static/dist/emacs-wiki-latest.tar.gz)
or the latest Arch updates of emacs-wiki .  I haven't tested it with
the Swedish language environment, but accented characters in Wiki
links worked fine with UTF-8.

I'm just guessing here, but it might help if UTF-8 is the default
buffer encoding.  I have the following settings in my .emacs file to
accomplish this.

(setq default-buffer-file-coding-system 'utf-8)
(prefer-coding-system 'utf-8)

Ideally, you should be able to keep using the Swedish language
environment.

If Wiki links continue to not work, try customizing
`emacs-wiki-regexp-lower', `emacs-wiki-regexp-upper', and
`emacs-wiki-regexp-alnum', adding the extra characters that you need
to each of these variables.
