In my program, I have this string in entry:
var toto = "Loïc";
I would like to decode this String in order to have:
'Loïc'
How can I do that?

These are HTML character references, also known as “HTML entities”.
To decode (or encode) them in JavaScript, it’s best to use the he library. he (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. It supports all standardized named character references as per HTML, handles ambiguous ampersands and other edge cases just like a browser would, has an extensive test suite, and — contrary to many other JavaScript solutions — he handles astral Unicode symbols just fine. An online demo is available.
var input = 'foo © bar ≠ baz 𝌆 qux';
var output = he.decode(input);
console.log(output);
// → 'foo © bar ≠ baz 𝌆 qux'
(All this has nothing to do with the UTF-8 encoding, by the way. I’ve removed the tag from this question.)

à and à are entities numbers. You can use this:
var element = document.createElement('div');
element.innerHTML = toto;
console.log(element.textContent);
> "Loïc"

Note that this will only work in browsers, not in non-browser JavaScript environments such as Node.js. Also, it returns incorrect results in browsers that have buggy implementations of HTML entities. To ensure the results are correct, use a library.
Check out the built-in JavaScript function encodeURIComponent(str) and encodeURI(str).
var muUrl="http://www.google.com?ul=اردوان";
var myUrl2 = "http://XXXX.com/default.aspx?link=" + encodeURIComponent(myUrl);
In your case, this should work
