JavaScript - insert unicode character to string
6
points
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.
\u03c0that is equal toπ, - 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.
