What steps will reproduce the problem?
1. Use in plain text letters = Ö Ä (German)

3. Decrypt value and instead of Ö Ä we have ???

What is the expected output? What do you see instead?
we must have a correct value with letters ÖÄ

Quick Fix for good job.

package com.googlecode.gwt.crypto.util;

public class Str {
    private static int[] delta;

    public static byte[] toBytes(char[] inputChars) {
        byte[] out = new byte[inputChars.length];
        delta = new int[inputChars.length];
    for (int i = 0; i < inputChars.length; i++) {
        out[i] = (byte) inputChars[i];
            delta[i] = (int) inputChars[i] - out[i];
    }
    return out;
    }

    public static char[] toChars(byte[] in) {
    char[] out = new char[in.length];
    for (int i = 0; i < in.length; i++) {
            if (i < delta.length) {
                out[i] = (char) (in[i] + delta[i]);
            } else {
                out[i] = (char) in[i];
            }
        }
        return out;
    }
}

Thanks for your fix!

Checked it in, as well as a test that should keep this from happening again.
