The Chooser II application in ProDOS supports only the standard character set. It doesn't print foreign characters displayed on the screen. With AppleWorks GS, anything other than Draft will print as a bitmapped version of what is displayed on the screen. This allows you to print foreign characters.
The only other option is to get an application that supports foreign languages. For more information, search on "Claris".
