I have set imp to use with language chinese(Traditional), then
 the interface now change to chinese Traditional, but when I receive
 message that is" Content-Type: text/plain; charset="big5"", it seemed
 that IMP is not understand the content of the message, what it dispay
 is a complete of wrong letters.
     How can I set IMP correctly to support reading chinese Traditional 
 message with it?
     Thanks!
