[New-bugs-announce] [issue41115] Codecs should raise precise UnicodeDecodeError or UnicodeEncodeError

[Antoine Pitrou]

New submission from Antoine Pitrou <solipsis at pitrou.net>:

A number of codecs raise bare UnicodeError, rather than Unicode{Decode,Encode}Error. Example:

  File "/home/antoine/miniconda3/envs/pyarrow/lib/python3.7/encodings/utf_16.py", line 67, in _buffer_decode
    raise UnicodeError("UTF-16 stream does not start with BOM")
