New submission from Tim Rawlinson:
In Python 3.3 decoding of headers to unicode is supposed to be automatic but
fails in several cases, including one shown as successful in the documentation:
>>> msg = message_from_string('Subject: =?utf-8?q?=C3=89ric?=\n\n',
policy=default)
>>> msg['Subject']
'=?utf-8?q?=C3=89ric?='
>>> msg = message_from_string('To: =?utf-8?q?=C3=89ric
<f...@example.com>\n\n', policy=default)
>>> msg['To']
'=?utf-8?q?=C3=89ric?= <f...@example.com>'
Although the following works:
>>> msg = message_from_string('Subject: =?utf-8?q?Eric?=\n\n',
policy=default)
>>> msg['Subject']
'Eric'
Though this does not:
>>> msg = message_from_string('To: =?utf-8?q?Eric?= <f...@example.com>\n\n',
policy=default)
>>> msg['To']
'=?utf-8?q?Eric?= <f...@example.com>'
And just to prove some things are working as they should:
>>> msg = message_from_string("Subject:
=?gb2312?b?1eLKx9bQzsSy4srUo6E=?=\n\n", policy=default)
>>> msg['Subject']
'这是中文测试！'
