Hi, I ran into a problem that this library doesn't support unicode in path

I use:

1. Debian 9
2. Python 3.5.3
3. GitPython==2.1.10 (installed by pip3 install GitPython command)

i found old issue, similar to mine, but it doesn't helped me:
#532

Everything works just fine if i will use path without cyrillic letters.
Code what doesn't work:

#!/usr/bin/python3
import git
def main():

    repo = git.Repo.clone_from("https://github.com/gitpython-developers/GitPython.git",
        "/home/vlad/AltSTU-Submodules/Диплом/Microcontroller-Unit-Testing/scripts/")

if __name__ == '__main__':
    main()

Traceback (most recent call last):
