 /**  * 判断是否为中文字符    * @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;    }
