I think the issue is not so much whether the JDBC driver *can* handle
the encoding, as whether it knows what it needs to be doing right now.

If the JDBC driver needs to do anything different for one encoding than
another, then it needs to be informed of changes. We can debate what's
the most appropriate way to keep it informed, but I don't think we can
just ignore the need to inform it.
