And do you really believe that this is acceptable for the average customer?

I didn't propose to find something better.

RFC2231 (actually, a small profile of it) works just fine; it just seems 
that some UA vendors (MS, Apple) believe they don't need to implement it.

Yes, you can. You just need to use the proper API to access the file system.

Well, we have an I18N problem, and a solution for it (RFC2231). Some 
vendors implement it (FF, Opera), others don't. The question is: can we 
improve the documentation of Content-Disposition so that it becomes 
clear that RFC2231 support is required? Furthermore, should we simplify 
things by stating precisely what parts of RFC2231 are really needed (the 
line folding is not needed, and support for a single charset (UTF-8) 
would be sufficient)?

BR, Julian
