How to get the response body in utf8 format in firefox add-on using request

Question

I user request in firefox add-on and I got headers details but I don't know how to get response body can any one help me out. I got full text using response.text but I need it in utf8 format for example(in node we use encoding(utf8)). I tried json.parse, but it returns null, though I get response.text

You can see all the response object properties on this part of the page. I use response.json as it's already a JavaScript object (effectively the same as JSON.parse(response.text);)
