Log:	hardcode the sys.std{in,out,err} encoding to ascii when running the
	tests. Two reasons: 1. if you don't specificy the encoding, it ends
	up using locate.getpreferredlocale() to guess one. I don't think
	it's a good idea that the behavior of the tests depend on the locale
	settings

	2. importing locale is very slow on py.py. By using the explicit
	encoding, initializing the space takes ~3 seconds instead of ~10 on
	my machine
