That PEP is to override the locale and use utf8 unconditionally.  It
says, with regard to the pre-PEP state:

	UTF-8 is also the default encoding of Python scripts, XML and JSON
	file formats.

Unicode was the reason for much of the Python 3 pain; it seems unlikely
that many installations are defaulting to ASCII anyway...?
