[imp] IMP do not show attachment name with umlaute

[Samuel Wolf]

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).

%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<
   Content-Type: text/plain; charset=UTF-8; format=flowed; DelSp=Yes
   Content-Disposition: inline
   Content-Transfer-Encoding: 8bit
[...]
   Content-Type: application/pdf;
    name*=utf-8''Rechnung_Z%C3%A4hlervertrag_97775___20131002_0904.PDF
   Content-Disposition: attachment; size=79556;
    filename*=utf-8''Rechnung_Z%C3%A4hlervertrag_97775___20131002_0904.PDF
   Content-Transfer-Encoding: base64
%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<%<

Problem on Horde side or sender side?
