Yes, you are right. The BAD_PARAM exception is actually thrown by the
validateTypeString function, before it gets to marshalPyObjectString.

It clearly would be possible to extend omniORBpy for Python 2 to handle
unicode objects where strings are expected, but I really wouldn't
consider it worth the effort. Python 2 is end of life and everyone
should be on the way to Python 3 if they're not already there.
