295794 - Non-ASCII attachment file name not preserved

Status: RESOLVED DUPLICATE of bug 234681

(MailNews Core :: Internationalization, defect)

Description

[Peter Kirk]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041217

I received an e-mail from a contact in the former Soviet Union with a file name
including some non-ASCII characters. The file name was correctly displayed in
the attachments window. When I saved the attachment with "Save As", the correct
file name was displayed in the Save Attachment dialog. But when I actually saved
the file, the non-ASCII characters were replaced by underscores in the filename.
Note that I am using Windows XP which provides full system support for almsot
any Unicode characters in file names.

From the message source:
Content-Type: application/octet-stream; name="=?koi8-r?Q?67REV=ED=F01.PTX?="
Content-Transfer-Encoding: quoted-printable
Content-Disposition: attachment; filename="=?koi8-r?Q?67REV=ED=F01.PTX?="


Reproducible: Always

Steps to Reproduce:
1. Highlight the message with this attachment.
2. Right click on the attachment and select "Save As".
3. Accept the file name in the "Save Attachment" dialog.

Actual Results:  
The file was saved as 67REV__1.PTX, i.e. with the two non-ASCII characters
replaced by underscores.

Expected Results:  
The file should have been saved as 67REVМП1.PTX (I assume by pasting this
correct version here that Bugzilla accepts Unicode!), the file name as intended
by the sender.

(Tried to do a search for an existing bug, but after waiting and then
researching and typing all of the above I am still getting a message "Please
stand by ...")
