解码法语口音不适用于 utf-8

Question

I try to decode this very simple variable b'autorite nt\\syst\x8ame\r\n'

b'autorite nt\\syst\x8ame\r\n'
>>> t.decode('utf-8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8a in position 16: invalid start byte

But nothing is working, it should print autorite nt\\système but I cannot find a way to print it correctly

Answer 1

It isn't encoded as UTF-8. It might be cp437, or any of these: cp437, cp720, cp850, cp857, cp858, cp860, cp861, cp863, cp865 ( source )

>>> print(b'autorite nt\\syst\x8ame\r\n'.decode('cp437'))
autorite nt\système

Answer 2

You can use decode with utf-8 encoding and replacement rule.

t = b'autorite nt\\syst\x8ame\r\n'
t.decode('utf-8', 'replace')
