I noticed that IMAP folder names containing non-ASCII characters are represented incorrectly in VM. They work perfectly well, but the name that is displayed (and required for input) is messed up. For the German and French names I have in my account that's not so bad, but I wouldn't want to deal with Greek or Chinese names.
I explored the issue a bit and found that the folder names are not decoded from UTF-7 (which is what IMAP specifieds). The raw UTF-7 strings are used as Emacs strings. Inserting a simple utf7-decode produces a perfectly fine folder list, but then all actions on those folders fail because the folder names are not properly re-encoded in UTF-7. I stopped at that point because I don't have a good enough overview of IMAP folder handling in VM to decide at what level UTF-7 encoding and decoding should best be implemented. It's not a vital issue but still something that should be on the to-do list. Konrad.
