Ensuring 7 bit encoding

[Nicholas Cole]

I hope that this question has a trivial answer, but that people won't
mind me asking it here. I've been googling the subject, but can't
quite get a handle on it.

What do I need to do to ensure that emails are generated only in 7,
not 8-bit encodings?  I assume that I need to use
email.charset.add_charset , but can't quite work out what incantation
to give it.  Does anyone have any pointers?

Best wishes,

Nicholas

I'm not sure what it is you're asking. Does this answer your question?

>>> import email.message
>>> m = email.message.Message()
>>> m.set_payload("""A few lines
... of 7-bit text
...
... No high bit characters.
... """, 'us-ascii')
>>> print m.as_string()
MIME-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: 7bit

A few lines
of 7-bit text

No high bit characters.

This is a bug.
