Description

# Don't BASE64-encode UTF-8 messages so that we avoid unwanted attention from
# some spam filters.
Charset.add_charset('utf-8', Charset.SHORTEST, Charset.QP, 'utf-8')

The above bit of code in django.core.mail overrides the standard Python behaviour for utf-8 in the Python email module. It would be better to set the charset by calling set_charset() on the Message before sending if needed rather than a global override. This behaviour and assumption is not documented anywhere in Django as far as I can tell. I think this is a case of the framework being a bit too clever. Not everyone using Django is using the django email sending methods nor wants Django to (silently) change the system defaults.

For example, I use the standard Python email sending methods and was expecting the Python lib to behave as advertised but the encoding of my utf-8 messages kept coming out quoted-printable because of the override above.
