           Summary: XMLHttpReqeust does not support charset "x-user-
                    defined", which can facilitate loading of binary data
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
               URL: http://tlrobinson.net/misc/webkit/binaryXHR.html
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tom at tlrobinson.net


Firefox's XMLHttpRequest can load binary data by overriding the MIME type to
use "x-user-defined":

req.overrideMimeType("text/plain; charset=x-user-defined");

(http://mgran.blogspot.com/2006/08/downloading-binary-streams-with.html)

WebKit's XMLHttpRequest does not support this charset, so it defaults to
another, which results in some of the binary values greater than 127 being
mapped to incorrect values (see the red boxes in the test case).
