From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0rc2)
Gecko/20020510
BuildID:    20020510 RC2

A mail with this in the header (Ctrl-U for source):
[snip]
Subject: Re: Äntligen hemma (eller inte!)
Date: Mon, 29 Oct 2001 09:57:34 +0100
Mime-Version: 1.0
Content-Type: text/plain; format=flowed
[snip]
Doesn't show correctly. The overview shows:
Re: ???????????
Same does the Title of the Mail-window show. 
The preview of the mail shows instead:
Re: tligen hemma (eller inte!)

Some more example of mails that don't show correct subject.
Header (Ctrl-U in windows):
X-Mailer: Mozilla 4.05 (Macintosh; I; PPC)
MIME-Version: 1.0
To: [e-mail]
CC: [e-mail], [e-mail], [e-mail]
Subject: Nu får man inte ens ha sin mail ifred!
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: 8bit

Show like in the overview and window-title:
Nu f??????????????????????????

And when you look at the mail it shows:
Subject : Nu f man inte ens ha sin mail ifred!

Reproducible: Always
Steps to Reproduce:
1. All my mail with these kind of (broken?) headers shows like this. 

Actual Results:  Headers shows incorrectly or unreadable.

Expected Results:  Show the headers "as is" (Ctrl-U does!) or try to decode it
correctly. This is probably not Mozillas fault, I guess there are a lot of
broken MUA's out there that produce faulty headers and I think Mozilla should
handle them. Netscape4, Outlook, OE and other do handle them and show them
correctly.

I mean _Subject_ when I write headers in the last couple of sentences, sorry for
that.

Those are not MIME encoded.

Mime Headers should not contains 8bits characters, instead they should use
specific  encoding. That sound a problem with the sender email client but if
that problem occurs with several other email client, we should try to find a
solution.

Naoki, what's your advise?

If the header is not MIME (i.e. no charset specified) then the default charset
is assumed. There are two ways to set default. In the preference dialog for
message display, also in the folder property dialog (which overrides the
preference setting).

Without a screen shot, we cannot know how the subject is not shown for this header.
Subject: Ordererkännande från Dustin AB

Reporter, please attach a screen shot of the problem. Also, please tell us what
is your default charset in the pref.

I had no default charset. I've been using my Mozilla profile for quite some time
(since 0.9.4). 
I set the default to "Western (ISO-8859-1)" and restarted Mozilla and the
problem was solved! It was not a bug. User error, sorry about that.

A suggestion could be to set the default to ISO-8859-1 or whatever the user has
(OS dependent, I know) when generating a new Mozilla profile. 
(Maybe this is fixed i later releases).

>A suggestion could be to set the default to ISO-8859-1 or whatever the user has
>(OS dependent, I know) when generating a new Mozilla profile. 
It is default to ISO-8859-1 for US build. Localized builds set their own values.
Not doing OS dependent way, because the default charset name may not be
extracted from OS (e.g. we do not use windows-1252 or x-mac-roman as default
mail charset but use ISO-8859-1).
