decodeURIComponent(JSON.parse('"http\\u00253A\\u00252F\\u00252Fexample.com"'));
> 'http://example.com'Use String.fromCharCode() like this: String.fromCharCode(parseInt(input,16)). When you put a Unicode value in a string using \u, it is interpreted as a hexdecimal value, so you need to specify the base (16) when using parseInt.
