Answer 2

For html4 use:

<meta http-equiv="Content-Type"content="text/html;charset=ISO-8859-1">

Answer 3

You can use a <meta> tag like this:

<meta charset='utf-8'>

Answer 4

Html 5 uses utf-8 as default charset
even if not defined...

However, to define explicitly use meta tag with charset attribute
