[Pkg-mailman-hackers] Bug#903100: Fix mailman charset encoding in subscription confirmation request mails

[bgrpt3 at toplitzer.net]

Package: python-django-mailman3
Version: 1.1.0-4~bpo9+1
Severity: normal

Mailman does not encode the initial subscription confirmation mail.
All other UserNotification-instances are created with correct
language in place.
