We should be able to encode the filename header per RFC 2047, but no browsers currently support it. So for non-ASCII filenames, we'll omit this header, and good browsers will use the filename from the URL, for which they know the proper encoding. MSIE will only understand a filename URL-encoded in the header, which is weird, but some user-agent matching fixes that.
