title: Is there any benefit to adding accept-charset="UTF-8" to HTML forms, if the page is already in UTF-8?
body: <p>For pages already specified (either by HTTP header, or by meta tag), to have a Content-Type with a UTF-8 charset... is there a benefit of adding <code>accept-charset="UTF-8"</code> to HTML forms?</p>
  
  <p>(I understand the <code>accept-charset</code> attribute is broken in IE for ISO-8859-1, but I haven't heard of a problem with IE and UTF-8. I'm just asking if there's a benefit to adding it with UTF-8, to help prevent invalid byte sequences from being entered.)</p>
