Best practice way to open files in Python 2.6+?

Under Python 2.6.4 (Windows), "io.open is open" returns False.
Retrieving help() on io.open and open() reinforces that these are
2 different implementations of open.

My use case is reading and writing UTF-8 text files with
universal newline support. I believe that the following io.open()
parameter list is what I should be using:

# mode set to 'rt' (read) or 'wt' (write)
io.open( file, mode, encoding='utf-8', errors='ignore',
newline=None )
