Public bug reported:

When TestCase.assertThat is invoked with a unicode string and a
DocTestMatches instance, the _with_nl() call made by the
DocTestMatches.match() method fails if the argument 'actual' is a
unicode string.

class MyTestCase(TestCase)
  def myTest(self):
     foo = u"foo\u2026"
    self.assertThat(foo, DocTestMatches(foo)) 

Trackback:
