Your problem consists of two parts:
- how to convert a Java String between Java's standard encoding and
ISO-8859-1 (or some other -x)
- how to plug this conversion into JAXB's marshalling and unmarshalling.
I trust that you can manage the first part by referring to JDK Javadoc
java.nio.charset.Encoder and ...Decoder.
For the second, see the JAXB tutorial:
https://jaxb.dev.java.net/tutorial/section_5_6_1-Overriding-the-Datatype.html
You go from String to String, doing the encoding conversion by calling
encode and decode in the parseUTF2ISO and printISO2UTF methods your
CharsetConverter class has to implement. The bindings file has to be
included in the xjc call (option -b *pathname*).
If this isn't sufficiently clear, come back with your questions.
