   * Escapes a code point that has no direct explicit value in the replacement array and lies
   * outside the stated safe range. Subclasses should override this method to provide generalized
   * escaping for code points if required.
   *
   * <p>Note that arrays returned by this method must not be modified once they have been returned.
   * However it is acceptable to return the same array multiple times (even for different input
   * characters).
