Same as the following, except "%MappedType wchar_t" and other obvious changes. 
You'd only have to write it once - all conversions will be handled correctly 
wherever wchar_t is referenced. 

%MappedType longlong
//converts a Python long
{
%TypeHeaderCode
typedef long long longlong;
#if PY_MAJOR_VERSION >= 2 && PY_MINOR_VERSION >= 3
#define LONG_LONG  PY_LONG_LONG
#endif
%End
%ConvertFromTypeCode
    if (!sipCpp)
        Py_INCREF (Py_None);
        return Py_None;

    return PyLong_FromLongLong (*(LONG_LONG *)sipCpp);
%End

%ConvertToTypeCode
    if (sipIsErr == NULL)
        return PyLong_Check (sipPy) || PyInt_Check (sipPy);

    long long *ll = new long long;
    *ll = 0;

    if (PyLong_Check (sipPy))
        *ll = PyLong_AsLongLong (sipPy);
    else if (PyInt_Check (sipPy))
        *ll = (long long)PyInt_AS_LONG (sipPy);

    *sipCppPtr = ll;

    return 1;
%End

};
