Subject: Added send_pgp_mime.Mail.encodedMIMEText() for unicode handling.
X-Git-Tag: v0.2~13
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=6815fa63c28a467b91824320a76e9f1e3bb7a0b3;p=pgp-mime.git

Added send_pgp_mime.Mail.encodedMIMEText() for unicode handling.

Now be-handle-mail handles examples/unicode without crashing
  cat examples/unicode | ./be-handle-mail -o -l -
But the output email is encoded in base64:

MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64

This is perhaps the best we can get out of python < 3.1/2.7, see
