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).
Reminds me of this thread: < http://my.opera.com/community/forums/topic.dml?id=118971 >
The solution at the end was to detect IE via the user agent header, do IE's way for the filename and do the RFC 2231 way for others. But, that's assumes UTF-8 URL encoding is turned on in IE.
It'd be nice if IE supported the RFC 2231 way.
