You may be able to get "δ" (and other Greek characters) to work on your system with 2.7, but if you want to be able to work with any filename on Windows, get Python 3.4 or later and use text strings, not byte strings.

Windows filenames are unicode strings and are stored, I believe, with utf-16 encoding. Even in early 3.x versions, there were Windows path problems, for instance with east Asian characters. Multiple 3.x patches seem to have fixed the problems. So merely using unicode is not, in general, sufficient.
