This bug is new to Mozilla 1.1 final, it was NOT present in 1.1 beta. Messages with iso-8859-2 character coding contain odd symbols instead of correct diacritics, but only when wieved in the preview window. After opening the message all characters are displayed properly. This may also apply to other character codings - haven't tested this.

Created attachment 97020 [details] Message window screenshot This screenshot shows the message window displaying the msg as it should look like, with proper character coding.
Mail/News has iso-8859-2 set as default character coding to use but the "ignore character coding specified by MIME header" option is disabled. iso-8859-2 is also on the list of active character codings. Messages coded with "Windows-1250" display odd both in preview and message window.
Everything works fine with a clean installation.
