New submission from Marko Lalic:
When the message's Content-Transfer-Encoding is set to 8bit, the
get_payload(decode=True) method returns the payload encoded using
raw-unicode-escape. This means that it is impossible to decode the returned
bytes using the content charset obtained by the get_content_charset method.
It seems this should be fixed so that get_payload returns the bytes as found in
the payload when Content-Transfer-Encoding is 8bit, exactly like Python2.7
handles it.
>>> from email import message_from_string
>>> message = message_from_string("""MIME-Version: 1.0
... Content-Type: text/plain; charset=utf-8
... Content-Disposition: inline
... Content-Transfer-Encoding: 8bit
...
... ünicöde data..""")
>>> message.get_content_charset()
'utf-8'
>>> message.get_payload(decode=True)
b'\xfcnic\xf6de data..'
>>> message.get_payload(decode=True).decode(message.get_content_charset())
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfc in position 0: invalid
start byte
>>> message.get_payload(decode=True).decode('raw-unicode-escape')
'ünicöde data..'
