Actually, in light of that we might want to override PGCLIENTENCODING to
SQL_ASCII, so we get back the results in ASCII (assuming an all-ASCII
test), instead of whatever the client encoding might say, which might
not be an ASCII superset.

But I still don't see a use case for the user setting the client
encoding when the test suite is run.  This can only make things worse,
not better.

Yes, that would make sense in any case.
