[imp] Attachements from Thunderbird to Imp with french characters

[Otto Stolz]

Hello list,

I had included a picture as yet another test case with my reply,
so it became too large for the list.

Here it is again, without the picture.

Best wishes,

Hi Jaques,

you have written:
> User-Agent: Thunderbird 1.5.0.5 (Windows/20060719)

This is indeed the most recent version.

> Content-type: image/jpeg; name*=ISO-8859-1''%E9t%E9.jpg
> Content-transfer-encoding: base64
> Content-disposition: inline; filename*=ISO-8859-1''%E9t%E9.jpg

The name, and filename, parameters comply with RFC 2231
<http://rfc-ref.org/RFC-TEXTS/2231/chapter4.html>.
So, any recent, standard-complying MUA should under-
stand them.

Note however that, according to RFC 2183,
> It is important that the receiving MUA not blindly
> use the suggested filename. The suggested filename
> SHOULD be checked (and possibly changed) to see
> that it conforms to local filesystem conventions,
> does not overwrite an existing file, and does not
> present a security problem

But this certainly does not explain that strange
filename your Imp has proposed, for this example.

Your little test has shown that the problem must be
on the receiving side, as the header lines of your
specimen seem entirely correct to me.

However, I cannot locate your problem any more
precisely. My Imp 3.2.2 installation does not
recognize that filename, at all, and my Imp 4.1.2
test installation recognizes it and proposes
"été.jpg", as expected. So, for these installatíons,
a French filename works as designed.

I'll include another example comprising a German umlaut
with this note, so you have another test case.
Note: "Säule" is a dialect term, meaning "piglet".

Best wishes,
