       * @param c
       * @return
       */
      public  boolean isChinese(char c) {
          Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
          if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
                  || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
                  || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
                  || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION
                  || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
                  || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {
              return true;
          }
          return false;
      }
