Charset Declaration

Checks for a declared character set (e.g., UTF-8).

What is this check?

A character set (or charset) declaration tells the browser how to interpret the text characters in your HTML file. UTF-8 is the universal standard.

Why is it important?

If you don't declare a charset, or use the wrong one, special characters, symbols, and different languages may not display correctly, appearing as gibberish or strange symbols.

What is the impact?

This is a critical technical issue. Incorrect character rendering makes your content unreadable and provides a very poor user experience.

Example Implementation

<head>
  <meta charset="UTF-8">
</head>
