Nevermind, I was testing with the wrong version of python.  This bug was introduced somewhere after 3.4 :(

>>> from email.message import EmailMessage
>>> m = EmailMessage()
>>> m['Subject'] = 'Hello Wörld! Hello Wörld! Hello Wörld! Hello Wörld!Hello Wörld!'
>>> bytes(m)
b'Subject: Hello =?utf-8?q?W=C3=B6rld!_Hello_W=C3=B6rld!_Hello_W=C3=B6rld!?=\n Hello =?utf-8?=?utf-8?q?q=3FW=3DC3=3DB6rld!Hello=3F=3D_W=C3=B6rld!?=\n\n'
