    The accepted answer is kind of wrong, depending on the encoding of the document. If no encoding is sent by in the HTTP header, the browser has to determine the encoding from the document itself.

    If the document uses a <meta http-equiv="Content-Type" … declaration to declare its encoding, then any ASCII-valued character (character code < 128) occurring before this statement must be an ASCII value, as per HTML 4 spec. Therefore, it's important that this meta declaration occurs before any other element that may contain non-ASCII characters.

    I recently was having a problem with a draggable jquery ui element. It was behaving properly in Firefox, but not Safari. After a ton of trial and error, the fix was to move my css links above the javascript links in the head. Very odd, but will now become my standard practice.

    If you declare the charset in a meta element, you should do it before any other element.

    Put the meta tag that declares the charset as the first element in head. The browser only searches so far for the tag. If you have too much stuff before the meta element, the charset might not get applied.

    If you use the BASE element, put it before any elements that load URIs (if desired).

    For the purposes of validation as XHTML, yes. Otherwise you're probably going to care about the optimization answers.

    It's recommended to put the meta tag with the character encoding as high as possible. If the encoding is not included in (or differs from) the response header of the requested page, the browser will have to guess what the encoding is. Only when it finds this meta tag it knows what it is dealing with and it will have to read everything it has already parsed again.

    See for instance Methods for indicating the character set.
