User Agent: Mozilla/5.0 (Windows NT 5.1; rv:5.0) Gecko/20110706 Firefox/5.0 SeaMonkey/2.2
Build ID: 20110706120824

Steps to reproduce:

En email sent from Sea Monkey  2.2 (at home) received with SM 2.2 (at work) displays the message subject with Czech characters wrong. The subject line is word dest (the s is with hook). When I view the message subject in viewer, it shows:
"Subject: =?ISO-8859-2?Q?d=E9=B9=BB=2E=2E=2E?="

Actual results:

displays the subject with Chiese characters (see attached picture).

Expected results:

The subject should display correctly all international characters. 

Maybe error should be on side of SM when entering the subject, or in the receivng SM.

Can you please add such a broken message from the sending computer to this bug?
(E.g. go to your Sent folder, hit CTRL+S, save it as an .eml file and attach it.)

When you compose such a message (on the sending computer), what's your setting in the editor's Options → Character Encoding?
On the receiving computer, what's your setting in the main mail window's View → Character Encoding?

> When I view the message subject in viewer

What's „viewer“? View → Message Source (CTRL+U)?
If so, then

> Subject: =?ISO-8859-2?Q?d=E9=B9=BB=2E=2E=2E?=

is just the internal representation for such characters, here "ISO-8859-2 as Quoted Printable". The "d=E9=B9=BB=2E=2E=2E" part decodes to "déšť..." under normal circumstances. Was that the original subject?

I so, then I can confirm this by these steps:
- compose message in ISO-8859-2 with subject "déšť..."
- save message as draft
- thread pane show subject as "d鹻...", obviously thinking that the subject is in UTF-8 and decoding it as such

the erroroneous email from sent folder

 When I want to save the email, SM offered the filename chinese too as transfered from the subject. The filename I have changed to be displayed without czech chars.

Hello Karsten,
doing as you have written.
The preferences (character encoding) set on the sending computer are: 
Message sending Central European CP 1250
Composing messages Central European CP 8859-2.
I do not know why both are different, maybe it has changed when upgrading.
I confirm the wrong display of the subject in the send folder of the sending computer.
Yes, the original subject was déšť (in czech it means rain).
If any other questions, let me know.
Decoding using some web decoders gives me the correct result.

Opening the saved message with Earlybird 7.0a2 gives me Chines chars.

I think we can confirm this.

The problem is sure in the sending SeaMonkey, as I have written before. What is interesting, that in the home SM I was not able to set the Composing messeges for Central European (Windows 1250), the listing does not offer it and it is much shorter than at work, so that is the reason for mixed setting as above. I will look at it again.
