Charset

[oo7ml]

What exactly is a charset? I have googled it but i still don't understand how important it is.

Which is the best one to use A or B ?

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

or

B:
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />


thanks in advance
