Will not work for uncode code points above 255.
Aye. But one could write a little loop to collect bytes until a complete
character was received. A little experiment:
>>> try: bytes((0xf0,)).decode('utf8')
... except UnicodeDecodeError as e:
... e2=e
...
>>> e2
UnicodeDecodeError('utf-8', b'\xf0', 0, 1, 'unexpected end of data')
>>> e2.reason
'unexpected end of data'
Keep collecting while you get `UnicodeDecodeError`s with a `.reason` of
'unexpected end of data'. Can be encoding agnostic (obviously you need
to _choose_ an encoding, it is needn't be utf-8).
(For the OP: `UnicodeDecodeError` doesn't necessarily mean you're
decoding Unicode data, you're decoding _into_ a Python string which is a
Unicode string.)
