It was a mistake that is corrected in Python 3.3. You can now use u'' to create Unicode literals in both 2.x and 3.3 or better. This is a feature only designed for porting code though: you shouldn't use u'' in new code not intended for 2.x. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
