361349 - ver en-US 1.5.0.8 couldn't send attachment file with chinese character correctly

Status: RESOLVED DUPLICATE of bug 309566

(Thunderbird :: General, defect)

Description

[SUN Guonian]

User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322)
Build Identifier: Thunderbird 1.5.0.8 (Windows/20061025)

en-US version 1.5.0.8 (20061025)

when I send e-mail with attachment named with chinese characters,
I find some mail client (eg. formail, ver<6.0) couldn't display
the attachment correctly.

I find that "name" line is different between chinese character 
file name attachment and character ascii file name attachment.

with chinese character file name attachment:
--------------010703000604070706050000
Content-Type: application/msword;
 name*=GB2312''%D6%D0%CE%C4%B2%E2%CA%D4%2E%64%6F%63
Content-Transfer-Encoding: base64
Content-Disposition: inline;
 filename*=GB2312''%D6%D0%CE%C4%B2%E2%CA%D4%2E%64%6F%63


and with ascii character file name attachment:
--------------030804000304020903050201
Content-Type: application/pdf;
 name="817-5504.pdf"
Content-Transfer-Encoding: base64
Content-Disposition: inline;
 filename="817-5504.pdf"


and use zh-CN version 1.5.0.8 (20061025), the "name" line
is same like ascii character file name attachment :
--------------060806000707080102030808
Content-Type: application/msword;
 name="=?GB2312?B?NjMw19zM5cfQu7u3vbC4LmRvYw==?="
Content-Transfer-Encoding: base64
Content-Disposition: inline;
 filename="=?GB2312?B?NjMw19zM5cfQu7u3vbC4LmRvYw==?="


Reproducible: Always

Steps to Reproduce:
1. use en-US/1.5.0.8/windows XP write an e-mail to myself, with an attachment file named with chinese character.
2. check mail.
3. view message source.
4. find "name*" and "filename*".

Actual Results:  
with foxmail(a e-mail agent), I couldn't find the attachment.

This sounds like a duplicate of bug 309566 (foxmail need to support RFC2231).
