R. David Murray added the comment:
Actually, no, the local part cannot be in anything other than ascii (see RFC
5335, which desires to address this problem among others). Also, an encoded
word cannot occur inside quotation marks. If you correct those two bugs, you
can generate an RFC-valid
kxroberto added the comment:
now I tried to render this address field header
u'Name , abc@ewf, "Nameß" '
with
h = email.Header.Header(continuation_ws='')
h.append ... / email.Header.make_header via these chunks:
[('Name <', us-ascii), ('abc\xce\xa3', utf-8), ('@xy>, abc@ewf, "', us-ascii),
New submission from kxroberto :
the email.* package seems to over-encode international charset address fields -
resulting even in display errors in the receivers reader - ,
when message header composition is done as recommended in
http://docs.python.org/library/email.header.html
Python 2.7.2
