JavaScript - insert unicode character to string

6 points
Created by:

In this article, we are going to look at how to insert Unicode characters to string in JavaScript.

There are three different ways how to do it:

  • with escape character e.g. \u03c0 that is equal to π,
  • by pasting character directly to string,
  • by converting codes to a string.

Quick solution:

// ONLINE-RUNNER:browser;

var text = "π or \u03c0"; // U+03C0

console.log(text); // π or π

Note: it is important to put 4 digits after \u.

More complicated example

Space is represented by 0x20 (in hex) or 32 (in dec). It is necessary to add 2 additional zeros before code (e.g. \u0020).

// ONLINE-RUNNER:browser;

var text = "π and \u03c0 are\u0020equal"; // U+03C0 U+0020

console.log(text); // π and π are equal

Marked inserted Unicode characters: π and \u03c0 are \u0020 equal.
