347749 - German Umlauts in attachment filenames not handled properly

Status: RESOLVED DUPLICATE of bug 309566

(Thunderbird :: General, defect)

Description

[wzeikat]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.13) Gecko/20060417
Build Identifier: Thunderbird 1.5.0.5 (Windows/20060719)

After an update via the update mechanism from 1.5.0.1 to 1.5.0.5, German umlauts are handled differently in attachment filenames. This leads to the problem that - on an exchange 2003 server with the recipient's inbox, Outlook XP cannot read those filenames anymore and changes them to *********.DAT which causes problems when trying to open the file.

Either downgrading to TB 1.5.0.1 or not using an umlaut in the file name make the problem disappear.

Header with 1.5.0.5:
Content-Type: application/pdf;
 name*=ISO-8859-15''H%F6hen_Sickerbecken.pdf
Content-Transfer-Encoding: base64
Content-Disposition: inline;
 filename*=ISO-8859-15''H%F6hen_Sickerbecken.pdf

Header of an attachment without umlaut (ö replaced by o actually)
Content-Type: application/pdf;
 name="Hohen_Sickerbecken.pdf"
Content-Transfer-Encoding: base64
Content-Disposition: inline;
 filename="Hohen_Sickerbecken.pdf"

Note the '' vs. " and the missing trailing "quote" with umlaut.






Reproducible: Always

Steps to Reproduce:
1.Attach a file with an umlaut in its name.
2.Send it to a recipient on an exchange 2003 server.
3.Open the mail with Outlook XP and check the filename / try to open it.

Actual Results:  
File is shown as ATT606823.dat by Outlook.

Expected Results:  
File is shown with original file name:
Höhen_Sickerbecken.pdf
(thats an ö character, in case it doesnt get posted/displayed here correctly).
