An HTML character set (charset) defines the character encoding scheme used to interpret bytes into visible text, numbers, symbols, and international characters on web pages. UTF-8 is the universal standard character set for all modern web applications.
You declare the document character encoding using the <meta charset="UTF-8"> tag placed at the top of the <head> section:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>UTF-8 Character Encoding</title>
</head>
Why UTF-8 is essential:
