Thanks again Kris,
if I understand correclty, the valid charset is the one computed by the
attached class. It seems to me that this is 191 characters long.
Could you please let me know where I am wrong?

class pgchars {
    public pgchars() {}
    static public void main(String[] args) {
        String x="ABCDEFGHIJKLMNOPQRSTUVWXYZ";

        x += x.toLowerCase();
        x += "0123456789";

        for (int i=2*8*8; i < 3*8*8+7*8+7; i++) {
            char[] c = { (char)i };
            x += new String(c);
        }

        x += "_$";

        System.out.println("final string size: " + x.length());
    }
