Comment:
Originally, being able to have unicode in attachment file names was added
in ticket #14964.
I tested this:
{{{
from django.core.mail import EmailMultiAlternatives
msg = EmailMultiAlternatives('Test', 'email body\nend',
'[email protected]', ['[email protected]'])
msg.attach_alternative('<html><body>email body<br>end</body></html>',
'text/html')
msg.attach(u'fíle_with_ünicöde_çhårs', b'foobar', 'application/octet-
stream')
msg.send()
}}}
and got following email body:
{{{

According to [https://tools.ietf.org/html/rfc2231 RFC 2231] that is
encoded correctly. My MUA also displays it correctly, so it seems to be an
error with Google and Zimbra.
