New submission from Antoine Pitrou <pit...@free.fr>:
Or, more precisely, it returns less than the requested number of
characters because characters are counted before translating newlines:
>>> f = io.StringIO("a\r\nb\r\n", newline=None)
>>> f.read(3)
'a\n'
TextIOWrapper gets it right:
>>> g = io.TextIOWrapper(io.BytesIO(b"a\r\nb\r\n"), newline=None)
>>> g.read(3)
'a\nb'
