Quoting Samuel Wolf <sam...@sheepflock.de>:
Hi,
receive sometimes mails with a attachment name which contains a
umlaut, but IMP do not show the attachments name
(no_attachment_name.png).
%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<
Content-Type: text/plain; charset="windows-1252"
Content-Transfer-Encoding: Quoted-Printable
[...]
Content-Type: application/octet-stream;
name="Rechnung_Z�hlervertrag_97775___20131002_0904.PDF"; type=Unknown
Content-Transfer-Encoding: BASE64
Content-Disposition: attachment;
filename="Rechnung_Z�hlervertrag_97775___20131002_0904.PDF"
%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<
If i send the attachment in a new mail to myself, IMP show the
attachment name, but this message is UTF-8 (attachment_name_ok.png).

Problem on Horde side or sender side?
sender. You can't send non-ASCII characters in mail headers.
We try to decipher the data from these broken clients, but it is not
100% successful (since the non-ASCII characters could very well have
been altered in transport). Generally, we run the data through both a
windows-1252 conversion and a UTF-8 conversion to see if that fixes
things. If your data was truly in windows-1252, then this would have
been automatically fixed for you. The fact that it isn't tells me
that the non-ASCII character has been altered since it was sent.
