request to Stack Overflow API returning weird response

I am using the following code to call the Stack Overflow API:

var request = require('request');
var url = 'http://api.stackexchange.com/2.2/search?order=desc&sort=activity&tagged=node.js&intitle=node.js&site=stackoverflow';
request({
    headers: {
        'Accept': 'application/json; charset=utf-8',
        'User-Agent': 'RandomHeader'
    },
    uri: url,
    method: 'GET'
}, function(err, res, body) {
    console.log("response.statusCode" + res.statusCode);
    console.log("response.headers" + JSON.stringify(res.headers));
    console.log("res" + JSON.stringify(res));
    console.log("resParse" + JSON.parse(res));
});

}

This code returns the response as weird chars :

res{"statusCode":200,"body":"\u001f�\b\u0000\u0000\u0000\u0000\u0000\u0004\u0000��{��H���\n�I�]M���̬U�5ݳ7=�3�ک�mݝN��L�t��\u0005\\\u001e�h��E��q�]����\\�\u0011�ɏxe��\"���\\���o�J?�\u001f���o�jq�X�����<���A?ݸv6Z���\u0012~F�N���v�?7�|��bq�ۢ��mՈ���Ŷ��Cj\u0016��b�I�\u001e��\u001b�����iY��\u001aw�\"Oҕ}H��ѝ\\Vզ�\r\u0002����m�c\u001b�����:�\bsJ\u0010f���\u0012��M\u001aW�¾w�߭t\u0001\u001an\u0016&-7+����)�_�Oz�}��\u0005�\\����*p�������\u0016�*���p�Y\u0006�m\u0007e-�?:��o\u0016i���rW��m�W��Y<�v�\u0010�۬��˛E3�;�n\u0016e�\u0017����e���*}J����\u0015\u001c��0,B���\".l��#����e}�-*\u0015��\u0018��gӉ�A'\u0013\u001c���\u0014��o\u001f3�undefined:1

Same code works for a different API call. Can someone suggest what's going wrong?

Stackoverflow uses compression to respond to your request. I've got the correct response using the following:

var request = require('request');
var url = 'http://api.stackexchange.com/2.2/search?order=desc&sort=activity&tagged=node.js&intitle=node.js&site=stackoverflow';
request({
headers: {
    'Accept': 'application/json; charset=utf-8',
    'User-Agent': 'RandomHeader' 
         },
     uri: url,
     method: 'GET',
     gzip: true
         },
  function(err, res, body) {
     console.log("response.statusCode" + res.statusCode);
     console.log('server encoded the data as: ' + (res.headers['content-encoding'] || 'identity'))
     console.log('the decoded data is: ' + body)  
   });
