dovecot - Nov 2009 - IMAP folders' codepages problem ?

Hi!

I probably have a problem with the imap folders codepages. I use polish email
clients such as MS Outlook and Windows Mail.
The clients try to create folders 

like Wiadomo?ci-?mieci but Dovecot creates Wiadomo&AVs-ci-&AVs-mieci

This happens on two different dovecot installations

1: Installation A

Please help :-) What should I do to have the right codes for the folder names?


Best regards

No, this is exactly what the client passes to Dovecot.  The IMAP standard
allows only plain ASCII in foldernames and therefor uses a modified UTF-7
encoding for non-ASCII characters.  See section 5.1.3 of RFC 3501.
