"it input" is a bit too general: Python applications can certainly
input and output Unicode, and any of its encodings.
But yes, you cannot really use UTF-8 in source code, for Unicode

In Python 2.2, non-ASCII bytes in a Unicode literal are always treated
as Latin-1. This is fixed in PEP 263, which allows you to write
# -*- coding: utf-8 -*-
Setting the source encoding in interactive mode is still not supported
by this PEP - it also somewhat depends on the console's encoding.

No. To use UTF-8 in source code, you have to write
In a larger source code fragment, this can be written as
return unicode(s, "utf-8")
b = u("å")
This relies on the fact that non-ASCII bytes in a string literal are
treated as-is; you should still declare the encoding, or else you'll
get a warning in Python 2.3.
