Regarding the Filename parameter, none of Asia language is taken into
consideration. As result, it is sort of nightmare in specially Japan.
Many copmanies use different encoding scheme. This is because none of
RFC does allow to use Asia character for file name as of today, it
allows only US-ASCII. 
Since using double-byte character is very natual in Asia countries as
file name. filename-paran := "filename" "=value" need to be more
considered to be able to accomodate non-US-ASCII character for value
field. MIME-2(Message Header Extensions for Non-ASCII) is defined as
extension for header field., I don't think this can be applied to this
"value".
It is time to say like
---------------------------------------------
disposition-param := filename-param
	/..............
filename-param := "filename" "=" dstring
dstring := 1*utf8
utf8 := <any sequence of octets formed from the UTF-8 transformation of
a character from ISO 10646>
---------------------------------------------
