The Kobo eReaders support various formats such as ePub, PDF and HTML, which theoretically makes it possible to read e-paper newspapers as long as they are in a compatible format. However, there is no specific support for e-paper newspapers such as the Berner Zeitung, which are often distributed via special apps or subscriptions. You should check whether the Berner Zeitung is available in one of the supported formats or whether there is a special app that works on the eReader.
