How to decode a mime part of a message and get a **unicode** string in Python 2.7?

Here is a method which tries to get the html part of an email message:
from __future__ import absolute_import, division, unicode_literals, print_function
import email
html_mail_quoted_printable=b'''Subject: =?ISO-8859-1?Q?WG=3A_Wasenstra=DFe_84_in_32052_Hold_Stau?=

Unfortunately I get a byte string. I would like to have unicode string.
According to this answer msg.get_payload(decode=True) should do the magic. But it does not in this case.

Unfortunately I get a byte string. I would like to have unicode string.
The decode=True parameter to get_payload only decodes the Content-Transfer-Encoding wrapper, the = -encoding in this message. To get from there to characters is one of the many things the email package makes you do yourself:
bytes = part.get_payload(decode=True)
charset = part.get_content_charset('iso-8859-1')
chars = bytes.decode(charset, 'replace')
( iso-8859-1 being the fallback in case the message specifies no encoding.)
