what should i do?

Answer 1

Your JSON deserializer is broken; \\uXXXX is supposed to be turned into proper characters.

To do that yourself, use this function

// Turns every occurrence of \uXXXX into a proper character
void UnencodeJSONUnicode(string str) {
    return Regex.Replace(str,
                         @"\\u(?<value>[0-9a-f]{4})",
                         match => {
                             string digits = match.Groups["value"].Value;
                             int number = int.Parse(digits, NumberStyles.HexNumber);
                             return char.ConvertFromUtf32(number);
                         });
}

(Untested code; I don't have VS available at the moment. Some exception handling would probably be nice too)

Looks like it has been JSON encoded, so you need to decode it. The DataContractJsonSerializer class can do this.

See this MSDN link for more information.
