This is slightly more complicated than that. UTF-8 is legal part of
local part of an email address, if SMTPUTF8 is used (as per RFC 6532).
Dovecot does not yet fully support UTF-8 in certain parts, particularly
we do not yet support RFC 6855 (IMAP Support for UTF-8), but we are
working on getting that to work, after which you can log in with UTF-8
usernames and passwords reliably.
