Hi Matz,

Do I have to put a header like

   # -*- coding: utf-8 -*-

into all my source files, or is there a command line option?

If I read from a file a string, it is automatically in US-ASCII encoding.
How do I change the encoding, e.g. if I know that the file is in UTF-8?

Regards,

   Michael
