How to convert unicode in JavaScript?

Question

I'm using the Google Maps API. Please see this JSON response.

The HTML instructions is written like this:

"html_instructions" : "Turn \u003cb\u003eleft\u003c/b\u003e onto \u003cb\u003eEnggårdsgade\u003c/b\u003e"

How can I convert the unicodes \u003c, \u003e etc. in JavaScript?

Answer 1

Those are Unicode character escape sequences in a JavaScript string. As far as JavaScript is concerned, they are the same character.

'\u003cb\u003eleft\u003c/b\u003e' == '<b>left</b>'; // true

So, you don’t need to do any conversion at all.

Answer 2

Below is a simpler way thanks to modern JS .

ES6 / ES2015 introduced the normalize() method on the String prototype, so we can do:

var directions = "Turn \u003cb\u003eleft\u003c/b\u003e onto \u003cb\u003eEnggårdsgade\u003c/b\u003e";

directions.normalize();

//it will return : "Turn <b>left</b> onto <b>Enggårdsgade</b>"
