I have modified my local build of boost.python to include a boost::python::unicode class, together with appropriate conversions from wchar, const wchar_t* and std::wstring, together with additional tests in the boost.python test suite. As you would expect, the code is closely derived from the existing boost::python::str code but uses the Python C API for PyUnicode_Type rather than PyString_Type. There are no breaking changes to the existing boost.python API. I'd like to contribute these changes back to boost.python so they can be hopefully integrated into future official Boost releases. What is the procedure for this? Where do I start?
