python - pyqt5 - QFileDialog - problem with greek characters in specified path

Question

In QFileDialog (pyqt5), there is a problem when the specified path has greek characters.

Example path: C:/Users/cpapp/OneDrive/Υπολογιστής -> select desktop

Problem:

I search in the web for the solution. It says to change some registry entries for desktop path. But i don't know what change should i apply, because the specified path may be correct.
