Hi,
   I agree with you. I have a Python unicode object in C (I don't know
which utf) and I want to convert this explicitely to utf-16. Is there
any way to do this?
PyUnicode_FromEncodedObject(PyObject *obj, const char *encoding, const
char *errors) says that obj can't be a unicode type so I guess I can't
use this one, does anybody knows any other method by which I can
achieve my goal?

Thanks,
