    1. Regex.Unescape(str);返回Unicode解码,非Unicode直接返回

    /// <summary>
          /// 2.转为Unicode编码
          /// </summary>
          /// <param name="str"></param>
          /// <returns></returns>
      public static  string ToUnicode(string str)
        {
            var  strResult = new StringBuilder();
          if (string.IsNullOrEmpty(str)) return strResult.ToString();
          foreach (var  t in str)
          {
              strResult.Append("\u");
              strResult.Append(((int)t).ToString("x"));
          }
          return strResult.ToString();
        }
          /// <summary>
          /// 3.Unicode 解码
          /// </summary>
          /// <param name="str"></param>
          /// <returns></returns>

                  string[] strlist = str.Replace("\", "").Split('u');
                  try
                  {
                      for (int i = 1; i < strlist.Length; i++)
                      {
                          int charCode = Convert.ToInt32(strlist[i], 16);
                          strResult.Append((char)charCode);
                      }
