OK. I think I can go that one better and avoid the UTF-8 conversion and 
save a little memory too. How about this:

    public Node copy() {

        Text copy;
        if (this.isCDATASection()) {
            copy = new CDATASection();
        }
        else {
            copy = new Text();
        }
        copy.data = this.data;
        return copy;

    }

(This also needs the addition of a non-public no-args constructor in 
CDATASection.)

This would share the data array between the original node and its copy. 
However, this array is private and is never written to inside the class. 
 It is occasionally replaced, but there's no way to change its 
contents. (The Text class is like a String in this respect). Thoughts?
