[Python-ideas] RFC: bytestring as a str representation [was: a new bytestring type?]

[INADA Naoki]

FYI, I can make sample data that is not roundtrip easily with iso2022-jp
encoding.

In [5]: b'\x1b$B\x1b(B'.decode('iso2022_jp')
Out[5]: ''

In [6]: b'\x1b$B\x1b(B'.decode('iso2022_jp',
'surrogateescape').encode('iso2022_jp', 'surrogateescape')
Out[6]: b''
