Fixes - Vanilla CallbackPollingTransport does not encode message.
Now encoding the message value with encodeURIComponent().
var url = packet.url;
url += url.indexOf('?') < 0 ? '?' : '&';
url += 'jsonp=' + callbackName;
- url += '&message=' + packet.body;
+ url += '&message=' + encodeURIComponent(packet.body);
script.src = url;
script.async = packet.sync !== true;
script.type = 'application/javascript';
