Hi,

That's unfortunate problem. The API requires byte streams, while
os.path.exists requires unicode. The obvious solution is to
encode/decode at either place, but the key problem is which encoding we
should use? Any ideas?

No expert, but I would go with 'utf-8' as that is also the Py3 default for class 'str' when bytes or bytearray is passed in.
