retry_failed_fields methods fails to produce meaningfull error if exception message contains unicode chars

[jbzdak@…]

Method south.orm.FakeOrm.retry_failed_field fails to produce meaningfull error if field raises exception that contains unicode chars during creation.

Faulty code is

   try:
       field = self.eval_in_context(code, app, extra_imports)
   except (NameError, AttributeError, AssertionError, KeyError), e:
       # It's failed again. Complain.
       raise ValueError("Cannot successfully create field '%s' for model '%s': %s." % (
           fname, modelname, e
       ))

You should either use unicode pattern:

raise ValueError(u"Cannot successfully create field '%s' for model '%s': %s." % (
           fname, modelname, e
       ))

or use repr:

raise ValueError(u"Cannot successfully create field '%s' for model '%s': %s." % (
           fname, modelname, repr(e)
       ))
