Here's a problem that plagued me a few years ago, and I'm pretty sure the situation hasn't improved since then, at least not in IE. Maybe HTML5 should say something about it. Use case: have the UA offer a "save as" dialogue, including the filename. Mechanism: Content-Disposition HTTP header, as defined in RFC2616 (<http://greenbytes.de/tech/webdav/rfc2616.html#rfc.section.19.5.1>) Example: Content-Disposition: attachment; filename=fname.ext Problem: this works fine in all browsers, as long as the filename does not contain non-Latin1 characters. RFC 2231 (<http://greenbytes.de/tech/webdav/rfc2231.html>) defines an escaping, and that is supported by Firefox. Example: Content-Disposition: attachment; filename*=utf8''D%C3%BCrst.ext IE does not support RFC 2231 (as of IE7), but allows percent escaped UTF-8, such as in: Content-Disposition: attachment; filename=D%C3%BCrst.ext However, that only works when IE is configured for UTF-8 URL encoding, which is (as far as I recall) not the default in countries using Asian languages. Proposal: require UAs to support RFC 2231 (UTF-8 variant). BR, Julian
