  It's not more awkward than RFC 2047 for simple cases.

Content-Disposition: attachment; filename*=utf-8''abc%b3%80.txt

Content-Disposition: attachment; filename="=?utf-8?q?abc=b3=80.txt?="

It's not its awkwardness but mostly the ignorance that kept it from
being implemented, IMHO.

So, what do you recommend? Using 'raw' UTF-8 chars in http header is 
reasonable  but using 'raw' non-ASCII/non-UTF-8 encodings must be avoided.
