org.pdf4j.saxon.tinytree.CharSlice
This is an implementation of the JDK 1.4 CharSequence interface: it implements a CharSequence as a view of an array. The implementation relies on the array being immutable: as a minimum, the caller is required to ensure that the array contents will not change so long as the CharSlice remains in existence. This class should be more efficient than String because it avoids copying the characters unnecessarily. The methods in the class don't check their arguments. Incorrect arguments will generally result in exceptions from lower-level classes.

        int doneto=0;
        while (i<len-2) {

                nextReceiver.characters(new CharSlice(array, doneto, i+2-doneto), 0, chprop);
                nextReceiver.characters("]]><![CDATA[", 0, chprop);
                doneto=i+2;
            } else if (array[i]==0) {
                nextReceiver.characters(new CharSlice(array, doneto, i-doneto), 0, chprop);
                doneto=i+1;
