Well this works for me. I had a little look in the code
and it seems buggy to me, at least the 3.2 version is.
There is a _encode but (1) The bytes generator version
is defined to allways use us-ascii as encoding and (2)
I couldn't find it actually being called on a mesg part.

recipient = "..."
sender = "..."
msg = MIMEText(txt)
msg.set_charset("utf-8")
msg['Subject'] = 'Python email tets'
msg['From'] = sender
msg['To'] = recipient
s = smtplib.SMTP('localhost')
s.sendmail(sender, [recipient], msg.as_string().encode("utf-8"))
s.quit()
