An end user should always be using the IDN version.  punycode is only  
intended as an intermediary for transport purposes and is not intended  
for human viewing.

I would assume it's an issue with the login command being used.  UTF-8  
can't be used with IMAP LOGIN (see RFC 6855 [5]).  An imap debug log  
(see imp/config/backends.php) would be useful to see if/where this is  
the case in the IMAP protocol conversation.
