You can't imagine how much of a relief it was to notice that importing didn't barf on the Swedish characters sometimes in the logs and/or files (this was an absolute nightmare when trying to convert to SVN/SVK).
yes, i remember marc talking about that and i tried to find out what the issue was as i had no problems importing to git.
Weird, I had no such problems whatsoever when making my Subversion import. All you need to do is put --encoding=latin1 on the commandline of cvs2svn (this is needed because CVS does not store any information about what charset it is using for metadata, neither implicitly nor explicitly).
