You don't need u('') in 2.6 - why do you think you need it there?

If you don't implement this PEP, you can have, uniformly across 2.6, 2.7 and all 3.x versions, 'xxx' for text and b'yyy' for bytes. For 2.6 you would have to add "from future import unicode_literals", and this might uncover places where you need to change things to use bytes or native strings - either because of bugs in the original code, or drawbacks in a Python version where you can't use Unicode as keys in a kwargs dictionary, or some API that wants you to use str explicitly. But at least some of those places will be things you would have to address anyway, when porting, whatever the state of Unicode literal support.
