Attachment: Chinese Characters NOT displayed correctly

--> internationalisation. Perhaps this should go into mailnews though

Comment 3

The screen shot contains at least one message showing Chinese.
I think other messages do not have MIME charset specified in their headers or
incorrectlyt labeled.
Please set mail view default character coding to Big5. This makes all non
charaset labeled messages to use Big5.
If still not working, please set a checkbox below the mail view default. This
makes any messages to be treated as Big5.

Xianglan, could you take look at this bug?

Comment 5

[wacheo]

[e-mail], you are right. The messages having problem does not have
charset set to big5. Most of them are set to iso-8859-1. I tried setting the
default to big5 as you said but it doesn't seem to have any effect on the
message list. (trunk build 2000101521)

[nhottanscp]

Please also check the checkbox below the mail default charset and try again.

Did you restart mozilla after you set the view default set to big5?

Comment 8

[wacheo]

[e-mail]: I did check that checkbox and it didn't seem to affect the
message list.

[e-mail]: Yes, I did restart mozilla.

I saw some msgs with big5 header but can be read by setting the charset to 
GB2312. Need to investigate more.

Comment 10

[wacheo]

maybe 'charset override' is not working??
now seems that problem only occurs to messages with header:
	Content-Type: text/plain; charset=iso-8859-1
messages that does not have "Content-Type" header displays ok when default is
set to big5.

a question: if i select BIG5 in menu "View/Character Coding", is it supposed to
update the current message in "message list" and "header" pane, too? instead of
just update the "message preview" pane?

Comment 11

[nhottanscp]

"View/Character Coding" only applies to the current message, so thread pane
message list is not affected.

Override checkbox does not work for thread pane, this is a bug, so confirm the bug.

Comment 12

[ji]

It looks like charset override only fails for those incorrectly labeled msgs.

Comment 13

[nhottanscp]

Changed the summary since this is a generic problem.

Comment 14

[ji]

Naoki, for msg contents, charset override is not working either if the charset 
label is wrong.

Comment 15

[ji]

Tried it again. Charset overriding for msg contents is actually working except 
that you have to reload the msg after the view default charset is changed.

And charset overriding for envelope is not working if the header has a wrong 
charset label. If the header is not mime encoded at all, then overriding for 
envelope is working. I'll file a seperate bug for this.

Comment 16

[ji]

Bug 57086 has filed for the envelope overriding problem.

Comment 17

[nhottanscp]

I found there is already a bug for this.

*** This bug has been marked as a duplicate of 46362 ***

Comment 18

[nhottanscp]

Reopen because bug 46362 is not exactly a dup of this.

Comment 19

[nhottanscp]

Charset override per folder (and thread pane) to be set by a folder charset UI
bug 39756, mark this bug as wontfix.

Comment 20

[ji]

Marked it as verified.
