ISO-8859-1 vs. UTF-8?

Issue

What should be used and when? Or is it always better to use UTF-8? Or ISO-8859-1 still has importance in specific conditions?

Is the haracter set related to geographic region?

---

Is there a benefit to using the code @charset "utf-8";?

Or like this <link type="text/css; charset=utf-8" rel="stylesheet" href=".." />

at the top of the CSS file?

I found for this

If Dreamweaver adds the tag when you add embedded style to the document, that is a bug in Dreamweaver. From the W3C FAQ:

"For style declarations embedded in a document, @charset rules are not needed and must not be used."

The charset specification is a part of CSS since version 2.0 (may 1998), so if you have a charset specification in a CSS file and Safari can't handle it, that's a bug in Safari.

And add accept-charset in the form:

<form action="/action" method="post" accept-charset="utf-8">

And what should be used if I use the XHTML doctype?

<?xml version="1.0" encoding="UTF-8"?>

or

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

Solution

Unicode is taking over and has already surpassed all others. I suggest you hop on the train right now.

Note that there are several flavors of unicode. Joel Spolsky gives an overview.
