Support of unicode in then recipient names

Hi Dovecot Community,

We are using ltmp to deliver messages through postfix to dovecot. During testing we have found that dovecot does not understand recipient email address if it is composed from national symbols : e.g. ยจฆฟคฏข@ยจฆฟคฏข.ยจฆฟคฏข Question is are there any plans to either add native support for such email addresses or to translate it to punycode and then try to find such a recipient?
