Okay... that makes sense. Thanks again!

Subject: RE: IFS file to PF Member

When you give it a byte array, it doesn't do any conversion.  It assumes
that you've already done the conversion that you want and it writes it
out
as is.  It has no way of knowing what encoding was used in the byte
array
that you hand it.

Strings, on the other hand, are always encoded in Unicode in java so it
can
make the conversion for you.
