Summary: Source encoding rules are extreme.

Initial Comment:
According to the PEP 0263, a source code that contains
non-ASCII
characters (ord(ch)>127) and does not define an
encoding causes
DeprecationWarning. In the future, such code will cause
SyntaxError.

While I believe that the idea of defining source code
encoding is very
useful, I think that the current solution is
unnecessary extreme.

It is very unfriendly for beginners. Imagine a student that
types her first script:

name = raw_input("What's your name? ")   # russian
here, of course
print "Hi %s!" % name

Do not even try to convince me that she must define an
encoding
here. That feature would break any possibility to use
Python in schools.

Actually the source code encoding only affects Unicode
literals.
The above script works the same way with any defined
encoding,
so the warning for this code is unnecessary.

As a solution, I propose to issue DeprecationWarning
(or SyntaxError)
only when a non-ASCII character is contained in a
Unicode literal.
