convert unicode to character javascript code example

Example 1: convert string to unicode javascript

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.

Example 2: javascript unicode to string

//convert unicode to string

// using a variable
let unicodeString = "http\\u00253A\\u00252F\\u00252Fexample.com\u{1F4A9}\x61";
console.log(decodeURIComponent(JSON.parse('"' + unicodeString.replace(/\"/g, '\\"') + '"')));

// direct approach
console.log(decodeURIComponent(JSON.parse('"http\\u00253A\\u00252F\\u00252Fexample.com\u{1F4A9}\x61"')));
