184242 - Mail titlebar doesn't render wrong MIME-type subject properly

Status: RESOLVED WORKSFORME

(MailNews Core :: Internationalization, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021207

This bug extends bug 9449.
Mozilla can now render Unicode strings in window title in Unicode-based MS
Windows systems (great job!), but there's still a little problem.

If a mail's subject is in MIME-type but the encoding is wrong (cf attachment),
even if the user chooses the right encoding from "View" menu, mail-window title
bar won't reflect the change.

PS: I hesitated between "I18N" and "MIME" while choosing "Component".



Reproducible: Always

Steps to Reproduce:

Attachment: Encoding should be Big5 instead of Latin1

The subject should be in Big5, but MIME-type wrongly indicates it as Latin-1. 
If we use "View" > "Character coding" to force Big5, title bar still won't
reflect the change.

widget is unicode enabled.
mail/news app needs to send a correct unicode string to the title bar (widget) 
when the unicode decoder is changed manually.

So, what about this bug?

A little additional info to this bug:
after we've selected the correct encodage for the subject so that it's displayed
correctly inside the message pane, neither "Reply", "Reply All" nor "Forward"
would use the correct encoding that we've just specified.  They just use the
default one.

Attachment: Subject is in Big5 but without MIME type

Here's another test case, similar to the first one.

In this test case, the subject is in Big5 but without MIME-type, that's why in
the next image (left), you could see that the window title bar displays squares
and the Subject field has question marks.

Then after we choose the correct encoding, ie Big5, the Subject field displays
correctly but the title bar doesn't reflect the change, as you could see in the
image.

OTOH, once again, Reply, Reply-All and Forward don't care about what encoding
user has chosen :(

Attachment: Shows the results of the previous test-case

Comment 7

[Jungshik Shin]

this has little to do with bug 9449. it's purely a mailnews issue. 

David and Scott, is there any callback we can invoke to propagate the change
made in View | Character Encoding to  the message list pane and in the window
title bar?

Now it works correctly right away.
