Turns all string literals into unicodes globally. Do not be tempted to use
|
||||
this option as it will probably break your world. It also produces
|
||||
``.pyc`` files with a different magic number than normal. Instead, you can
|
||||
enable unicode literals on a per-module basis by using::
|
||||
|
||||
from __future__ import unicode_literals
|
||||
|
||||
at the top of the file. See :mod:`__future__` for details.
