code: @Deprecated
      public static boolean isNormalized(String str, Mode mode, int options) {
          return mode.getNormalizer2(options).isNormalized(str);
      }
docs: Test if a string is in a given normalization form.
  This is semantically equivalent to source.equals(normalize(source, mode)).
  
  Unlike quickCheck(), this function returns a definitive result,
  never a "maybe".
  For NFD, NFKD, and FCD, both functions work exactly the same.
  For NFC and NFKC where quickCheck may return "maybe", this function will
  perform further tests to arrive at a true/false result.
  @param str       the input string to be checked to see if it is
  normalized
  @param mode      the normalization mode
  @param options   Options for use with exclusion set and tailored Normalization
  The only option that is currently recognized is UNICODE_3_2
  @see #isNormalized
  @deprecated ICU 56 Use {@link Normalizer2} instead.
