Decode HTML character references in JavaScript string

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?

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

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"
