Issue 35670: os functions return '??' for unicode characters in paths on windows

I have a few files that contain emojis in their names, and also a folder that has such. Commands like `os.getcwd`, `os.listdir`, `os.path.realpath`, etc. will cause this to happen. However, this is only, as far as I can tell, happening on pure windows distributions. This does not happen in the cygwin64 version I have, nor does it happen in python3.

For example, say you have a folder simply called '🔭'. If you run python inside of it and run `os.getcwd()` you will simply get `'??'` as the result. This breaks MANY of my programs that depend on knowing exactly where they are, and knowing the contents of a directory to pass to other functions.
