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
