At least utf8 works with current musl, busybox 1.20.1 and dropbear. An example from my embedded system:

% id
uid=1999(рысь) gid=1999(рысь) groups=1999(рысь)

authpriv.notice dropbear[1010]: password auth succeeded for 'рысь' from 192.168.1.1:37173

OpenSSH is conservative (or paranoid) here, user names are escaped everywhere.
