But in the message pane (F8) they are displayed correctly. Also if message pane is configured to be opened in separate window, in a case of such messages the title also contains question marks instead of normal national text. I have marked it on the screenshots: http://i44.tinypic.com/2ppbg45.png http://i42.tinypic.com/2imax6v.png I can forward such messages to any email so you can test it. Reproducible: Always This is 2 .eml files which are displayed incorrectly: http://www.sendspace.com/file/2qg4ce http://www.sendspace.com/file/5yarv6

did this also happen in thunderbird 2.0.0.21?

Yes.

Non-ascii character should be properly encoded. => INVALID Note: In display at header box of message pane, "From: ..." header string and "Subject: ..." header string is rendered using HTML parser/renderer with auto-detect=on (XUL). And it happened to be detected as windows-1252 or mail body's charset=windows-1252 is used. So they are fortunately displayed as you want. To be tolerant with such malformed mails by bad mailers, Tb has a feature. Folder properties Default Character Encoding: windows-1252 [ X ] Apply default to all messages in the folder (individual message character encoding settings and suto-detection will be ignored) If you copy the mails to folder with this option(and rebuild-index if required), text you want is displayed at thread pane, and mail body is also readable if mail body is written in windows-1252.

(In reply to comment #6) Hi WADA, thanks for your response :) > Binary of non-ascii MUST NOT be put in From:/Subject: header. Non-ascii > character should be properly encoded. > => INVALID Yes, I also heard about it... But it's too much emails today sent this incorrect way. It would be impossible to convince all this people to fix their settings. I also see that some of the serious email-clients do workaround this problem. I think Thunderbird may do it too... Hope it will happen someday :) > To be tolerant with such malformed mails by bad mailers, Tb has a feature. > Folder properties > Default Character Encoding: windows-1252 > [ X ] Apply default to all messages in the folder (individual message > character encoding settings and suto-detection will be ignored) > If you copy the mails to folder with this option(and rebuild-index if > required), text you want is displayed at thread pane, and mail body is also > readable if mail body is written in windows-1252. Hmm, I tried this, but it doesn't help at all... Everything remains exactly the same. Pls see the screenshot. (Actually the encodings in my case are windows-1251, I knew it by saving eml files and using external text editor)

Do you execute rebuild-index? windows-1251 binary is really written in Subject: header? Possibly my misunderstanding. The folder property is applicable to mail body only. Interpretation of mail header may not be affected by the setting.

(In reply to comment #9) > Do you execute rebuild-index? Yes, even few times :) (Also tried restarting Tb) > windows-1251 binary is really written in Subject: header? Yes.
