This is why I gave the example using an unknown character set:
Content-Type: Message/External-body;
filename="=?unknown?Q?/usr/spool/xyz/ne=3d=3cfoo?"
The locale and character set of the filename is actually irrelevant to all
of this discussion. What is needed is to be able to pass a filename to the
system that will be recognized on that system. This only requires a way of
specifying an 8-bit quantity to be passed over a 7-bit wire, and the rfc
1342 mechanism does just fine for doing that.
You should give the character set together with the data,
or else nobody would konw what the filename is. anyway rfc1342
can do.
