I'm in favor of that, with the idea that by 3.1 or
3.later (depending on feeback from international
community), Python would eventually deprecate those
options, and it would eventually be the burden of
non-Unicoders (which includes me) to specify
--asciionly if they were worried about running
non-ASCII Python.

I disagree with option 1 (not quoted), but not
passionately.
