What it currently does:

>>> import email.utils
>>> email.utils.getaddresses(['Shuming [范書銘] <shumingf@realtek.com>'])
[('', 'Shuming'), ('', ''), ('', '范書銘'), ('', ''), ('', 'shumingf@realtek.com')]

What it should do:

>>> import email.utils
>>> email.utils.getaddresses(['Shuming [范書銘] <shumingf@realtek.com>'])
[('Shuming [范書銘]'), 'shumingf@realtek.com')]

Hi Konstantin,

Thanks for raising this issue. It appears the field provided in your example does not conform to RFC 2822 followed by this email library. Square brackets are treated as special characters in [section 3.2.1](https://tools.ietf.org/html/rfc2822#section-3.2.1), which is handled in the [_parseaddr](https://github.com/python/cpython/blob/master/Lib/email/_parseaddr.py#L219) file.

The above combined with the fact that any [failed parsing returns an two-tuple of ('', '')](https://github.com/python/cpython/blob/master/Lib/email/utils.py#L212) I believe explains the behavior observed.
