code: @Deprecated
      public static int compare(int codepoint, CharSequence a) {
          int result = compare(a, codepoint);
          return result > 0 ? -1 : result < 0 ? 1 : 0; // Reverse the order.
      }
docs: Utility to compare a string to a code point.
  Same results as turning the code point into a string and comparing, but much faster (no object creation).
  Actually, there is one difference; a null compares as less.
  Note that this (=String) order is UTF-16 order -- *not* code point order.
