* Performance note: ASCII test is *much* faster, as we can avoid expensive
* function call overhead. This is the hot case, so we try to do that
* whenever possible. As far as we know, *every* encoding we support
* is a strict superset of ASCII. So we can make things faster by trying
* ASCII first, and only then falling to locale specific checks.
