For eventual other people wanting a workaround, this is the code I used to leverage ``ctypes`` and redo what last python 3 code is doing. Any comment are welcome, this is my first go at ``ctypes``. I didn't extensively tested the code... so use at your own risk. The Gist might evolve if some people find issues:

Tests/Usecases are simple: use ``subprocess.Popen(..)`` to simply issue a ``git commit -am "ć"``. And display the changelog. You can also call another python script, that would then need this other recipe (this time to get ``sys.argv`` correctly encoded on windows):

Hope that helps.
