[issue10417] unittest triggers UnicodeEncodeError with non-ASCII character in the docstring of the test function

[Johannes Ammon]

New submission from Johannes Ammon <johannes.ammon at gmail.com>:

When there is a non-ASCII character in the docstring of a test function, unittest triggers an UnicodeEncodeError when called with "--verbose".

I have this file unicodetest.py:
-----------------------------------------
# -*- coding: utf-8 -*-
import unittest

class UnicodeTest(unittest.TestCase):
    def test_unicode_docstring(self):
        u"""täst - docstring with unicode character"""
        self.assertEqual(1+1, 2)

if __name__ == '__main__':
    unittest.main()
-----------------------------------------

Running it normally is ok:

$ python unicodetest.py 
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK


But with "--verbose" it breaks:

$ python unicodetest.py --verbose
