How is that possible on POSIX systems where the underlying file system
uses bytes for filenames?
If I write a piece of Python code:
filename = 'some path/some name'
I might call it a filename, I might think of it as a filename, but it
*isn't*, it's a string in a Python program. It isn't a filename until
it hits the file system, and in POSIX systems that makes it bytes.
