In a recent thread named "py3 tkinter Text accepts what bytes?"
(google groups link:
http://groups.google.com/group/comp.lang.python/browse_thread/thread/b75ed69f4e81b202/e2aff9ddd62d210c?lnk=raot)
I asked what kinds of bytes are accepted as tkinter parameters.
I still wonder why they are accepted at all.
Does anyone know a reason for this
or has a link to some relevant discussion?

Thanks for any hint,
Matthias Kievernagel
