How to convert string “\uFFFF” to Unicode?

Question

I am quite new to Javascript and easily get into trouble when dealing with string. I have done some research but it is difficult to get the solution and the best answer found in this site is in Java. I really need your help to make it in Javascript.

I started with this:

xmlHttp = new XMLHttpRequest(); 
xmlHttp.open("GET", sUrl, true);
xmlHttp.overrideMimeType('text/plain; charset=utf8');
xmlHttp.send(null);

The xmlHttp.responseText contains strings like "le t\ù di ch\ào" where the \ù</b> and \à are Unicode characters ( ù , à ).

How can I covert the xmlHttp.responseText into readable characters in Javascript?

Answer 1

Thanks to Niet the Dark Absol 's hint, I solved the problem.

xmlHttp.overrideMimeType('application/json');
obj = JSON.parse(xmlHttp.responseText);

document.getElementById('Content').innerHTML = obj.data[0].name;
