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.

import smtplib

from email.mime.text import MIMEText

txt = '''\
Het adres is

Fréderic Boëven
Frère Orbanstraat 17
'''

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()
