Can't send unicode email (HTML emails using EmailMultiAlternatives)

This is directly related to, but the steps differ:

from django.core.mail.message import EmailMultiAlternatives

# the character is some sort of fancy dash/hyphen
subject = body_text = body_html = u'\u2013'
e = EmailMultiAlternatives(subject, body_text, '', [''])
e.attach_alternative(body_html, 'text/html')

This results:

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2013' in position 0: ordinal not in range(128)

As with the referenced ticket above, the root cause must lie with; python 2.7.x works fine while 2.6.5 (on our production server running Ubuntu 10.04) it does the above. I assume that a similar fix is needed for attachments and not just text. I wonder if subject and to/from lines are similarly problematic?

Personally, I'd rather document the bug than working around outdated versions of Python. If anyone proposes a complete patch with tests, it has a chance to go in, otherwise it might end up as "won't fix"...

I can't reproduce this in python2.7, django 1.4.

comment:6 Changed 5 years ago by Claude Paroz

No, only Python < 2.6.6 is affected.

comment:7 Changed 5 years ago by Simon Charette

Resolution: wontfix
Status: newclosed

Marking as won't fix since no one wrote a complete patch as requested by @claudep and 1.7 is dropping support for Python 2.6.
