Yes and no.

That is the right method.

That is the symptom of a different, much bigger problem. Encoding problems
certainly never corrupt the clog.

That depends on where your throws come from. As you surely know, Java mostly
uses Unicode internally, so the data sent by the JDBC driver to the database
is in Unicode, but as to what encoding the data that you input into your Java
program has, you need to sort that out with the Java library functions that
you use to read that data.
