[Distutils] Providing binary packages for Python versions with different internal unicode representation

Hi, Python interpreters can be compiled by different internal unicode representations (UCS2 vs. UCS4). Extension modules using unicode methods of Python internally can not be used with a Python interpreter with a different internal unicode representation. What's the deal when you want to provide binary packages of an extension module for Python interpreters with different unicode representations....is there some support for doing this using setuptools?
