The problem is Notepad has a limited view of the text world. If you use
it only in the Microsoft universe and for simple tasks it is sufficient.
The issues arise when you try to work with files outside that scope. For
long term peace of mind you will better served by more capable text
editors(see other posts for suggestions). As to the Python
documentation, it goes on to say:
http://docs.python.org/tutorial/interpreter.html#source-code-encoding
"Notice that this signature is not understood in older Python releases
(2.2 and earlier), and also not understood by the operating system for
script files with #! lines (only used on Unix systems)."
From the Zen of Python:
"Explicit is better than implicit"
Following that the preferred way of declaring an encoding would be:
# -*- coding: utf-8 -*-
