About
A charset (character set) is a list of letters, numbers, and symbols that computers use to show and read text. It helps make sure the right characters appear, especially in different languages. For example, UTF-8 is a popular charset that works with many languages and symbols. Without the correct charset, websites may show weird symbols or question marks. Setting the right charset helps everyone read and understand the text properly.
Risks
Special characters show up as weird symbols.
Why it's important
Helps computers show words and symbols correctly in different languages and on different devices.
User stories
As a website visitor, I want the text to display correctly in my language so I can read and understand it easily.
Code
<head>
<meta charset="UTF-8">
