Status of SMTPUTF8?

[Noah Tilton]

I was wondering whether there is a roadmap for adding SMTPUTF8 support 
to Dovecot?

My delivery pattern is Postfix -> Dovecot LMTP and it is choking on utf8 
messages.

I might be able to volunteer some of my time as a developer.

Another thread about this seemed to go unanswered:
