[issue35016] \r to match add into address header with not-ascii character

2018-10-18 Thread Ivan Krivosheev 

New submission from Ivan Krivosheev :

When convert email.message.Message to bytes, into header with non-ascii 
character in address add to match *\r* symbol.

Simple script for reproduce problem:

>>> from email.message import Message
>>> from email.policy import SMTP
>>> msg = Message(policy=SMTP)
>>> msg['To'] = 'Юзер Один '
>>> print(msg.as_bytes())

On python 3.5 result:

>>> b'To: =?utf-8?b?0K7Qt9C10YAg0J7QtNC40L0=?= \r\n\r\n'


On python 3.6, python 3.7:

   >>> b'To:\r\n =?utf-8?b?0K7Qt9C10YAg0J7QtNC40L0=?= 
\r\r\r\r\r\n\r\n'
