Using TB 6 on Mac OS 10.6.5 I found that after uninstalling TB Conversations all my international Characters (Umlauts, etc.) are displayed wrong. Could anybody please give me a hint how to get this fixed?

Questa recensione riguarda una versione precedente (2.0.8) del componente aggiuntivo. 

I'm pretty sure this is unrelated to Thunderbird Conversations. Help for Thunderbird is at http://getsatisfaction.com/mozilla_messaging/
