Yes, we can do everything. But does it really have a sense? No Python function 
using filenames return a bytearray object. Example: os.listdir() and os.walk() 
result type is bytes or str.

Changing PyUnicode_FSConverter() is trivial, but the problem is in the 
function calling PyUnicode_FSConverter(). The caller have to support byte and 
bytearray. Antoine proposed to convert bytearray to bytes to ensure that 
PyUnicode_FSConverter() result is a bytes object. But in this case, we still 
need also to fix ntpath, ,posixpath and macpath modules to support bytearray.
