Comment (by Florian Apolloner):
Oh, it needs a non-ascii character to trigger encoding in the first place:
{{{
from django.conf import settings
settings.configure()
from django.core.mail.message import EmailMessage
e = EmailMessage('subject', 'content', '[email protected]', ['"TestUser
รค%s" <[email protected]>' % ('0' * 100)])
print(e.message().as_string())
}}}
raises
{{{
