Yes, it seemed to work with your original example, but of course you have to
encode unicode somehow before sending it through a wire. A severe case of
peephole debugging, sorry. I've looked into the email package source once
more, but I fear to understand the relevant parts you have to understand it
wholesale. 

As Max suggested, your safest choice is probably passing in utf-8 instead of
unicode.
