Sending file name containing unicode characters in http file download
Hi All,
I've an application which can be used for downloading file over web. Now
if the file name contains Unicode characters which are not in iso-8859-1
range, the name appearing at the browser (in the download window asking
for save) coming as junk.
I'm passing the fine name through http header by setting the filename
parameter. The code is written in JSP.
In this context I need to know following things -
1. As I was aware through http header one cannot send non
iso-8859-1 characters. Is this problem happening due to the same reason
?
2. If the answer to above Qs is yes, the what is the solution/work
around for downloading a file having name with Unicode characters which
are not in iso-8859-1 range in http file download ?
Any input/pointer would be highly appreciated.
Regards,
Sourav

You don't have any control over the client-side decoding; the browser
will look at the HTTP header and 'do it's thing' with it. There is a way
to do this, I think there's an encoding mechanism you can use for
non-ASCII header data. I'm not sure if it's standardized by HTML or one
of those 'by convention' things though.
Just had a quick look at some old code, which turned out not to be doing
exactly what I'd expect (!) but I *think* what you need to do is to
convert the filename into a byte stream using the request encoding, then
URL encode that byte stream and use the result as the filename in the
Content-Disposition header.

Sourav,
I'm not sure, but I'd guess that you'd want to encode it as a transportable
UTF-8 format on the server side, and decode it on the client side. Assuming
that this is, in fact, what you need to do, you can find instructions on
doing it here:

Good luck!
Daniel
