Fix weird unicode-related bug in tests

This test has been failing for me for ages:
`AssertionError: u'English (US) (default), Deutsch, Espa\xf1ol' != u'English (US) (default), Deutsch, Espa\xc3\xb1ol'
`

This fixes it for me, but I'm not sure what was going on or why it wasn't failing for others.
