I'm recieving the a JSON string in API response which is containing /n and / in between.
{\n  \"Return Code\" : \"Ok\",\n  \"Return Mess\" : \"No Error\",\n  \"Time Zone\" : \"SA\",\n  \"FNN Line Type Potent\" : \"AB\",\n  \"Number Of FNNs Returned\" : 5,\n  \"FNNs\" : [ {\n    \"fnnExt\" : \"122525\",\n    \"fnnNode\" : \"Node 1\",\n    \"technology\" : \"S\",\n    \"lastUsed\" : \"2017-04-25\",\n    \"workingStatusCode\" : \"R\",\n    \"remarks\" : \"No Remarks\",\n    \"disconnectReason\" : \"TD\",\n    \"quarantineDate\" : \"2017-06-05\",\n    \"quarantineIndicator\" : \"Y\"\n  }, {\n    \"fnnExt\" : \"225632\",\n    \"fnnNode\" : \"Node 2\",\n    \"technology\" : \"S\",\n    \"lastUsed\" : \"2017-08-04\",\n    \"workingStatusCode\" : \"R\",\n    \"remarks\" : \"No Remarks\",\n    \"disconnectReason\" : \"TD\",\n    \"quarantineDate\" : \"2017-08-02\",\n    \"quarantineIndicator\" : \"Y\"\n  }, {\n    \"fnnExt\" : \"552365\",\n    \"fnnNode\" : \"Node 3\",\n    \"technology\" : \"S\",\n    \"lastUsed\" : \"2017-07-06\",\n    \"workingStatusCode\" : \"R\",\n    \"remarks\" : \"No Remarks\",\n    \"disconnectReason\" : \"TD\",\n    \"quarantineDate\" : \"2017-02-26\",\n    \"quarantineIndicator\" : \"Y\"\n  }, {\n    \"fnnExt\" : \"225417\",\n    \"fnnNode\" : \"Node 4\",\n    \"technology\" : \"S\",\n    \"lastUsed\" : \"2017-01-05\",\n    \"workingStatusCode\" : \"R\",\n    \"remarks\" : \"No Remarks\",\n    \"disconnectReason\" : \"DD\",\n    \"quarantineDate\" : \"2017-02-10\",\n    \"quarantineIndicator\" : \"Y\"\n  }, {\n    \"fnnExt\" : \"441256\",\n    \"fnnNode\" : \"Node 5\",\n    \"technology\" : \"S\",\n    \"lastUsed\" : \"2017-04-02\",\n    \"workingStatusCode\" : \"R\",\n    \"remarks\" : \"No Remarks\",\n    \"disconnectReason\" : \"DD\",\n    \"quarantineDate\" : \"2017-06-04\",\n    \"quarantineIndicator\" : \"Y\"\n  } ]\n}

I am only using the Array part of JSON and i have a wrapper class for it as well.
I'm using below code to convert this Json Array to list of wrapper class.

 while (parser.nextToken() != null) {
            if (parser.getCurrentToken() == JSONToken.START_ARRAY) {
                while (parser.nextToken() != null) {
                    if (parser.getCurrentToken() == JSONToken.START_OBJECT) {
                        FNN fnnRecord = (FNN)parser.readValueAs(FNN.class);
                        String s = JSON.serialize(fnnRecord);
                        system.debug('Serialized -----> ' + s);
                        fnnlist.add(fnnRecord);
                        // Skip the child start array and start object markers.
                        parser.skipChildren();
                    }
                }
            }
        }

Now this peace of code works very well for if the JSON string doesn't contain /n and /. But since my response contains these characters the code is breaking.
Any solutions please.

Thanks
