UnicodeDecodeError when writing unicode to stdout of management command

[Darren Hobbs]

In a management command in Python 2.7, if you include unicode characters when writing to stdout (with self.stdout.write) you will get a UnicodeDecodeError

# coding=utf-8
from __future__ import absolute_import, unicode_literals

import sys

import pytest
from django.core.management.base import OutputWrapper
from django.utils.encoding import smart_bytes


def test_bad_unicode_case_names():
    bad_name = smart_bytes(u'£')
    ow = OutputWrapper(sys.stdout)
    with pytest.raises(UnicodeDecodeError):
        ow.write(bad_name)
