I don't think this has any lasting effect in interactive mode. Each 
statement is compiled and executed separatedly. In Idle, this is done 
with exec().

Better than what I get on my 3.4.1 Win7
U+20AC is € is 0x80 in CP-1252

# -*- coding: utf-8 -*-
print(u"U+20AC is € is 0x80 in CP-1252")
works

The problem is python exec, not Idle. Use the editor and submit coding 
and code together.
