How to insert Unicode in JavaScript
The Unicode Standard provides a unique number for every character, no matter the platform, device, application, or language. UTF-8 is a popular Unicode encoding which has -bit code units.
Unicode in Javascript
There are several ways that Unicode may be needed in Javascript. These include:
- Unicode in Javascript source code.
- Unicode in Javascript strings.
Code
Unicode in Javascript source code
In Javascript, the identifiers and string literals can be expressed in Unicode via a Unicode escape sequence. The general syntax is \uXXXX, where X denotes four hexadecimal digits. For example, the letter o is denoted as ‘\u006F’ in Unicode. Hence, to write the letter “foo” in Unicode, we can use the following code.
var f\u006F\u006F = 'abc';console.log(foo)
Unicode in Javascript strings
Just like in source code, Unicode can also be represented in a Javascript string using the \uXXXX syntax. The following code assigns a special Unicode character (a cow) to the variable abc.
var str = '\uD83D\uDC04';console.log(str)
