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 accept-charset="UTF-8" to HTML forms?
(I understand the accept-charset 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.)
