How to print unicode json using Javascript

Question

I try to print JSON response in my html document so I do:

respdiv.innerHTML = '<pre><code>' + xhr.responseText + '</code></pre>';

The problem is my response is printed like this :

{ "error": "Sc\\u00e9nario invalide" }

I want my response to be printed like this :

{ "error": "Scénario invalide" }

How I get this?

It sounds like you need to fix the problem on the server. Can you make the server return the response in UTF-8 or not escape the \ characer? — p.s.w.g

You can delegate all the work to JSON.parse() then unescape the characters:

var responseText = unescape(JSON.parse('"' + xhr.responseText + '"'));
respdiv.innerHTML = '<pre><code>' + responseText + '</code></pre>';

But as @p.s.w.g suggested, I would advice fixing it on server side.

You can provide the snippet that made it work in order to help future readers, think community :)

Sure it won't work on the provided fiddle with my hook just because you are trying to parse a JSON object ({ "error": "Sc\\u00e9nario invalide" }) while I wrote a snippet to only unescape a straightforward string object. You got it? Take a look at this version of you fiddle, jsfiddle.net/fsh6s/1 and compare it to yours. You will see the difference.
