How to Convert Unicode Values to Characters in JavaScript

In this article, you will learn how to convert unicode values to characters in JavaScript.

Converting unicode values to characters in JavaScript

Unicode is a character encoding standard that assigns unique numbers to each character. In JavaScript, you can convert Unicode values to characters using built-in functions.

Using the fromCharCode() method

The first method is using the fromCharCode() method to convert a Unicode value to a character. Here is an example code snippet:

const unicode = 65;
const char = String.fromCharCode(unicode);
console.log(char); // Output: "A"

Explanation

• String.fromCharCode(unicode) converts the Unicode value to its corresponding character.
• The Unicode value 65 represents the character “A”.

Using the String.fromCodePoint() method

The second method is using the fromCodePoint() method to convert a Unicode value to a character. Here is an example code snippet:

const unicode = 128522;
const char = String.fromCodePoint(unicode);
console.log(char); // Output: "😊"

Explanation

• String.fromCodePoint(unicode) converts the Unicode value to its corresponding character.
• The Unicode value 128522 represents the emoji “😊”.

Using the Unicode escape sequence

The third method is using the Unicode escape sequence to convert a Unicode value to a character. Here is an example code snippet:

const unicode = 127775;
const char = "\u{1F31F}";
console.log(char); // Output: "🌟"

Explanation

• “\u{1F31F}” is the Unicode escape sequence for the star emoji “🌟”.
• The Unicode value 127775 represents the star emoji “🌟”.
