I'm still learning python and I have a doubt:
In python 2.6.x I usually declare encoding in the file header like this (as in PEP 0263)
# -*- coding: utf-8 -*-
After that, my strings are written as usual:
a = "A normal string without declared Unicode"
But everytime I see a python project code, the encoding is not declared at the header. Instead, it is declared at every string like this:
a = u"A string with declared Unicode"
What's the difference? What's the purpose of this? I know Python 2.6.x sets ASCII encoding by default, but it can be overriden by the header declaration, so what's the point of per string declaration?
Addendum: Seems that I've mixed up file encoding with string encoding. Thanks for explaining it :)
