It seems the only solution I have is to open the file in UTF-8 mode (generating a .h file). It looks like Windows does not recognize those characters if not generated from UTF-8.

Right, I hadn’t realized that python on Windows doesn’t handle UTF8 automatically.

According to this article setting PYTHONUTF8=1 might help?
