The stdlib wants any non-ASCII encoding passed to the testsuite
constructor, e.g. (this is from Lib/test/test_doctest.py in Python 2.6)::

   If the tests contain non-ASCII characters, we have to specify which
   encoding the file is encoded with. We do so by using the `encoding`
   parameter:

     >>> suite = doctest.DocFileSuite('test_doctest.txt',
     ...                              'test_doctest2.txt',
     ...                              'test_doctest4.txt',
     ...                              encoding='utf-8')
     >>> suite.run(unittest.TestResult())
