I'm OK with a way to change the default to something locale-specific,
as long as there's also a way to make the default strict ASCII (for
export).  Maybe python -A could force the default encoding to be ASCII
even if the locale specifies something different.

(I'd still *prefer* it the other way around, where you have to specify
an explicit option to make the default equal to the locale rather than
ASCII, but I can see the other side.  Sigh.)
