Unable to post multi line comment on Chatter FeedItem using Chatter REST API

I am trying to post a simple text comment to FeedItem. The comment has line breaks.

Following is my code:
 
String comment = 'Test1\r\n\r\nTest2';

String access_token = AuthController.getJIRAOAuthToken();

String authVal = 'OAuth '+access_token;
HttpRequest req = new HttpRequest();
String endpoint = system.label.JIRA_OAuth_SFDC_REST_API_Endpoint+'/services/data/v35.0/chatter/feed-elements/';


System.debug(endpoint); 
req.setEndpoint(endpoint);
req.setMethod('POST');
req.setHeader('Content-Type','application/json; charset=UTF-8');

req.setHeader('Authorization', authVal);




req.setBody('{"body":{"messageSegments":[{"type":"Text","text":"'+comment+'"}]},"feedElementType":"FeedItem","subjectId":"a3gm0000000066S"}');


Http http = new Http();
//System.debug(req);
HTTPResponse res = http.send(req);
System.debug('**'+res);

I am getting below response.
System.HttpResponse[Status=Bad Request, StatusCode=400]

If I am trying the same code without "\r\n" then it works perfectly fine. Any suggestions please ?


I tried replacing "\r\n" with " " as per the rich text feed item https://developer.salesforce.com/docs/atlas.en-us.chatterapi.meta/chatterapi/quickreference_post_feed_element_rich_text.htm but even that didn't help. The comment is posted along with " " in text.
