Mmmh, the fix requires to change PyUnicode_AsWideChar() function (support non-BMP characters and surrogate pairs) (and maybe also to create PyUnicode_AsWideCharString()). I don't really want to change such important function in a stable branch (Python2).

Is it really important to support non-BMP characters for ctypes.c_wchar in Python2? I would like to say: if you want better unicode support, use Python 3. And Python 3.2 if it's possible :-)
