[issue7643] What is an ASCII linebreak?

[Florent Xicluna]

New submission from Florent Xicluna <laxyf at yahoo.fr>:

Bytes objects and Unicode objects do not agree on ASCII linebreaks.

## Python 2

for s in '\x0a\x0d\x1c\x1d\x1e':
  print u'a{}b'.format(s).splitlines(1), 'a{}b'.format(s).splitlines(1)

# [u'a\n', u'b'] ['a\n', 'b']
# [u'a\r', u'b'] ['a\r', 'b']
# [u'a\x1c', u'b'] ['a\x1cb']
# [u'a\x1d', u'b'] ['a\x1db']
# [u'a\x1e', u'b'] ['a\x1eb']


## Python 3

for s in '\x0a\x0d\x1c\x1d\x1e':
  print('a{}b'.format(s).splitlines(1),
        bytes('a{}b'.format(s), 'utf-8').splitlines(1))

['a\n', 'b'] [b'a\n', b'b']
['a\r', 'b'] [b'a\r', b'b']
['a\x1c', 'b'] [b'a\x1cb']
['a\x1d', 'b'] [b'a\x1db']
['a\x1e', 'b'] [b'a\x1eb']
