20407 2008-08-15 15:59:00 -0700 Safari/Webkit doesn't support Non US-ASCII filenames in Content-Disposition header 2008-08-15 16:54:10 -0700 1 1 1 Unclassified WebKit WebCore Misc. 528+ (Nightly build) All OS X 10.5 RESOLVED DUPLICATE 15287 P2 Normal --- 0 rpaplin webkit-unassigned oldest_to_newest 88609 0 rpaplin 2008-08-15 15:59:00 -0700 As per RFC 2184 & 2231, if one wants the web browser to properly display a filename that contains Unicode characters in the File Download dialog box, you must encode the filename as URL-encoded UTF-8 in the Content-Disposition field. Let's say I want to download an image named 2008年8月8日.jpg The server should send down the following header Content-Disposition: attachment; filename*="2008%e5%b9%b48%e6%9c%888%e6%97%a5.jpg" In Firefox it works as expected (Note: it appears Firefox supports multiple ways of encoding international filenames. For example, the following header also gives the desired result. Content-Disposition: attachment; filename="2008\345\271\2648\346\234\2108\346\227\245.jpg" In IE, if you omit it the asterisk after the filename filed it works (like so).. Content-Disposition: attachment; filename="2008%e5%b9%b48%e6%9c%888%e6%97%a5.jpg" I've yet to see this work in Safari using any web application (I've tried Gmail, Hotmail, Windows Live Skydrive) or any of the above methods. 88611 1 mrowe 2008-08-15 16:54:10 -0700 *** This bug has been marked as a duplicate of 15287 ***
