Python 2 is EOL, so I think this issue should be closed.

Mike,

Thank you.

I moved to Python 3 some time ago.  I confirm that Python 3 does not
have the problem.  But I can't conveniently verify your workaround for
Python 2.

[Mike Edmunds]

Mike Edmunds  added the comment:

Here's a workaround for Python 2.7:

```
class HeaderBugWorkaround(email.header.Header):
def encode(self, splitchars=' ', **kwargs):  # only split on spaces, rather 
than splitchars=';, '
return email.header.Header.encode(self, splitchars, **kwargs)

# and then...

msg['Subject'] = HeaderBugWorkaround(subject, 'utf-8', header_name='Subject')

```

(If you have the option, you're almost certainly better off moving to Python 3 
for anything email related. But if you're maintaining code that has to be 
Python 2.7 compatible, this might help.)

R. David Murray added the comment:

No, that is python3 code, it doesn't work on python2.  There's no workaround 
other than to back port the fix.

Matthew Jacobi added the comment:

Is there a workaround for this for people on python2? 
Would installing https://pypi.python.org/pypi/email/6.0.0a1 fix it?

[issue25257] In subject line email library inserts unwanted space after a thousands comma in a number

[R. David Murray]

R. David Murray added the comment:

This is fixed in Python3.  The fix was part of a large change to the header 
folding algorithm, and I'm not sure it is appropriate to backport it.  I'm 
guessing we would, though, if someone wants to do the work for the backport.  
The relevant issue is issue 11492.

[issue25257] In subject line email library inserts unwanted space after a thousands comma in a number

[Bob Hossley]

New submission from Bob Hossley:

In my function makeMsg(), there is:

msg = email.mime.nonmultipart.MIMENonMultipart('text',
'plain', charset='utf-8')
msg['Subject'] = email.header.Header(subject, 'utf-8')

subject has no space after the thousands comma:

u'1,010 words - "The Blackmail Caucus, a.k.a. the Republican Party" By Paul 
Krugman'


But

msg['Subject'].__str__()

'1, 010 words - "The Blackmail Caucus,\n a.k.a. the Republican Party" By Paul 
Krugman'

has a space after the thousands comma and the email message later generated has 
a space after the thousands comma.

This is objectionable.

Note that the email library also inserts a newline after the comma that is 
followed by a space.  Since I see no effect of this newline on the email 
generated, I have no objection to the newline.

Thank you R. David Murray.

I look forward to being able to move my application to Python 3.
