Status: UNCONFIRMED

(Thunderbird :: Message Reader UI, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.224 Safari/534.10
Build Identifier: 3.1.7

Before update everything was fine. I use polish language and receive many messages encoded as ISO-8859-2, this is my basic setting for encoding in received messages. However messages encoded this way are displayed without polish characters. I've seen the sources of messages, encoding was set as ISO-8859-2 - after changing the view for encoding as ISO-8859-2, the messages are displayed correctly. It seems thet Tb doesn't use the default settings/or doesn't recognize (I've tried with different default encoding and it didn't change anything) the encoding and displays it in "its own" way. It works like this only with some of the messages, as far as I see it's only the plain text ones.

Reproducible: Always

Steps to Reproduce:
1. Set default character encoding for received messages to ISO-8859-2
2. Receive plain text e-mail encoded in ISO-8859-2 with polish characters (ąśćńół etc.) in the title and the body
3. Polish characters are not displayed correctly
4. Check the settings for the view of the message to view it as ISO-8859-2 and everything works fine - the problem is you have to do it manually and Tb doesn't do it automaticly - as it did defore an update.
