JSONP: Escape JSON String

Assume you have a JSON string that you are going to send as result value back to Javascript, then you need to do the following:

        String dataString = stringWriter.toString();
        dataString = dataString.replaceAll("\\u2028","\\\\u2028");
        dataString = dataString.replaceAll("\\u2029","\\\\u2029");

Basically, you need to escape the unicode characters.
