The question is how tenable the illusion is. If the OS gave the appropriate guarantees (say, all pathnames are encoded Unicode strings), the abstraction could be maintained. Unfortunately, the legacy shines through making you wonder if Python has overreached prematurely with its Unicode HAL. Marko -- https://mail.python.org/mailman/listinfo/python-list
