I have no idea why it's doing what it's doing. The lesson appears to be: don't use the compat32 mode unless you have to support Python 3.2 (which you don't, because that's ridiculous) >>> msg 'Subject: =?utf-8?q?=C3=89lys=C3=A9e?=\nContent-Type: text/plain; charset="utf-8"\nContent-Transfer-Encoding: 7bit\nMIME-Version: 1.0\n\nTEST MESSAGE\n' >>> p = email.parser.Parser(email.message.EmailMessage) >>> p.parsestr(msg)['Subject'] '=?utf-8?q?=C3=89lys=C3=A9e?=' >>> p = email.parser.Parser(email.message.EmailMessage, policy=email.policy.default) >>> p.parsestr(msg)['Subject'] 'Élysée' >>> Simple. Silly. Simply silly. I've been confused by the unicode handling of this module before...
