We are not 'reintroducing' unicode literals. In Python 3, string 
literals *are* unicode literals.

Other developers reintroduced a now meaningless 'u' prefix for the 
purpose of helping people write 2&3 code that runs on both Python 2 and 
Python 3. Read about it here http://python.org/dev/peps/pep-0414/

In Python 3.3, 'u' should *only* be used for that purpose and should be 
ignored by anyone not writing or editing 2&3 code. If you are not 
writing such code, ignore it.

You are the one making it be a problem.

The simultaneous reintroduction of 'ur', but with a different meaning 
than in 2.7, *was* a problem and it should be removed in the next release.

Except that many public libraries that we would like to see ported to 
Python 3 have not been. The purpose of reintroducing 'u' is to encourage 
more porting of Python 2 code. Period.
