Ok, I just tried it. It's a pain because you need to reboot (hmm, actually
I bet all you need to do is restart the server service, oops) for the
changes to take effect.

Result: The plaintext password is Unicode. The password should be encoded
like any other string but it seems Samba wants ASCII. I tested this with
JCIFS and an ASCII password with everything else Unicode works. Everything
in ASCII works. Everthing in Unicode does not work.
