There are available three different ways how to do it:
- with escape character e.g.
\u03c0that is equal to
- by pasting character directly to string,
- by converting codes to string.
// 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
More complicated example
Space is represented by
0x20 (in hex) or
32 (in dec). It is necessary to add 2 aditional zeros before code (e.g.
// 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\u0020equal.
