248639 - Setting Outgoing format to UTF-8 causes all text attachments to be sent base64

Status: NEW

(MailNews Core :: Composition, defect)

Description

[Kelley Cook]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.9
Build Identifier: Mozilla Thunderbird 0.7 (Windows/20040616)

If the default outgoing character set is Western European, which of course is a
superset of 7 bit ASCII, then a plain ASCII text attachments will be sent as an
inline 7bit text.

However, if default outgoing character set is UTF-8 (which is also a superset of
ASCII) then that same plain ASCII text attachments will be sent base64 encoded.

Reproducible: Always
Steps to Reproduce:
1. Set Mozilla to Western European with Tools -> Options -> Fonts -> Outgoing
Mail: Western (ISO-8859-1)
2. Create a new message with a pure ASCII attachment such c:\boot.ini. 
Attachment will be formatted:
Content-Type: text/plain;  name="boot.ini"
Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="boot.ini"
3. Change to UTF-8 with Tools -> Options -> Fonts -> Outgoing Mail: Unicode (UTF-8)
4. Create a new message with a pure ASCII attachment.  Attachment will be formatted:
Content-Type: text/plain;  name="boot.ini"
Content-Transfer-Encoding: base64 Content-Disposition: inline; filename="boot.ini"


Actual Results:

Expected Results:  
Both methods should have been sent the attachment via 7-bit ASCII as both
character sets are a superset of ASCII.

I'd start debugging around here:

Comment 8

The route for step 1 is now: Tools - Options - Display - Formatting - (Fonts) Advanced - Outgoing messages

I created an ASCII file in Powershell by redirecting Get-Process output to a file:

GPS | Out-File -FilePath c:\ascii.txt -Encoding ASCII

The encoding, however, is UTF-8 as verified in multiple programs and also in TB.

This is for ISO-8859-1:
Content-Type: text/plain; charset=UTF-8;
 name="ascii.txt"
Content-Transfer-Encoding: 7bit

This is for UTF-8 (still repro):
Content-Type: text/plain; charset=UTF-8;
 name="ascii.txt"
Content-Transfer-Encoding: base64
