The email module, when creating text parts using character encoding utf-8, base64-encodes the output even though this is often inappropriate (e.g. if it is a Western language it is almost never appropriate).

>>> from email.mime.text import MIMEText
>>> m = MIMEText("hello", _charset="utf-8")
>>> m.as_string()
'Content-Type: text/plain; charset="utf-8"\nMIME-Version: 1.0\nContent-Transfer-Encoding: base64\n\naGVsbG8=\n'

Yes, this sub-optimal, but it's the way it works in the legacy API, and we aren't going to change the legacy (compat32) API at this point.  The new policies and the new API in python3 handle this sensibly.

Just a note for anyone finding this in searching results: it appears that what David means by "python3 API" is actually a new API in Python 3.6 (email.message.EmailMessage).

The API exists in python3.5 and python3.4 as well, it was just provisional.  Very few things changed between the provisional version and the final version in 3.6.
