How do you indicate the character set being used by an HTML5 document? How does this differ from older HTML standards?

Question

Concerned about the difference !!

Answer 1

In HTML5, just put
<meta charset="UTF-8">
in the head of the page. For HTML4, you can use

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
