TypeScript - insert unicode character to string

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

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:

xxxxxxxxxx

const text: string = 'π or \u03c0'; // U+03C0

​

console.log(text); // π or π

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

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

xxxxxxxxxx

const text: string = '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.
