New submission from skreft <skr...@gmail.com>:
The docs
(https://docs.python.org/3/library/email.util.html#email.utils.formataddr) say
that formataddr is the inverse of parseaddr, however non-ascii email addresses
are treated differently in both methods.
parseaddr will return non-ascci addresses, whereas formataddr will raise a
UnicodeError.
Below is an example:
In [1]: import email.utils as u
In [2]: u.parseaddr('skreft+ñandú@sudoai.com')
Out[2]: ('', 'skreft+ñandú@sudoai.com')
In [3]: u.formataddr(u.parseaddr('skreft+ñandú@sudoai.com'))
