While I see how the conversion would benefit your Java programs, I do have
a certain concern... unicode requires two physical bytes of storage for
each character.  If you have large character fields, this could
significantly increase your DASD requirements.

Also, what's the legacy system downside?  Doesn't this actually ADD
conversion requirements to legacy systems?

There is a certain sense of "baby with the bathwater" in switching the
storage technique for character data in order to improve performance.
