UnicodeDecodeError when parsing email with "\u" in its body

[dcfreire]

Using parse_from_file or parse_from_bytes in an email containing "\u" raises UnicodeDecodeError

Steps to reproduce the behavior:

1. import mailparser
2. mail = mailparser.parse_from_file(f)
3. See error

Expected behavior Mail is properly parsed

I'm having a related issue with an email too. Interestingly enough, I can load the email using python's native email reader.

Error is triggered in the same place:

    444                         cte = cte.lower()
    445                     if not cte or cte in ['7bit', '8bit']:
--> 446                         payload = payload.decode('raw-unicode-escape')
    447                     else:
    448                         payload = ported_string(payload, encoding=charset)
