1. Prevent crashing from UnicodeDecodeError …

   On Python 2, `sys.stdout` and `print` can normally handle any
   combination of `str` and `unicode` objects. However,
   `StringIO.StringIO` can only safely handle one or the other. If
   the program writes both a `unicode` string, and a non-ASCII
   `str` string, then the `getvalue()` method will fail with
   `UnicodeDecodeError` [1].
   
   In nose, that causes the script to suddenly abort, with the
   cryptic `UnicodeDecodeError`.
   
   This fix catches `UnicodeError` when trying to get the captured
   output, and will replace the captured output with a warning
   message.
   
   Fixes nose-devs#816
