"invalid byte sequence in UTF-8" when rsyncing files with international character

[dbackeus]

I'm using capistrano to run rsync to sync files from a remote server to my local disk. As soon as the rsync reaches a filename with an international character (in this case the Swedish letter ö) it outputs this error:

The exact filename that it barfs on is Hövding-65x42.png.

After outputting the error it appears that rsync keeps running in the background but the output stays frozen with the error.
