I'm russian, but it seems that this problem spreads to all non-iso-8859-1 chars.
My mail server users got a lot of folders named in russian. The create them with Outlook, thunderbird, the bat! and other modern mail applications via IMAP protocol.
look at screens 1) and 2) -- the all illustrates that roundcube perfectly shoes them up (I repeat - created in some application).
the look at the third screen -- there are some encoded symbols. this happen when I tried to edit russian name. the same happen when anybody try to create a russian-named folder.
I suppose this could be easily fixed, but since I'm not as good in PHP as I wish I'm asking you to help with this issue.
