Senf introduces a new platform native string type called fsnative. It adds functions to convert text, bytes and paths to and from that new type and helper functions to integrate it nicely with the Python stdlib.
Senf supports Python 2.7, 3.4+, works with PyPy, works on Linux, Windows, macOS, is MIT licensed, and only depends on the stdlib. It does not monkey patch anything in the stdlib.
