Well, yes in that the PEP will only be implemented in 3+, but the motivation was to make a single codebase easier to achieve. It does that if you take the narrow view of 2.6+/3.3+, but not if you factor 3.2 into the mix. Maybe 3.2 adoption is too low for us to worry about here, but I for one certainly wish it hadn't been relegated to being a 2nd-class citizen. > The u"" fixer will just be one more tool in the arsenal of those that > *do* want to support 3.2 (either because they want to target Ubuntu's > LTS 3.2 stack, or for their own reasons).

Right, I get that - as I said, unicode_literals is my preferred path of the options available. It's a shame to see this sort of Balkanisation, though. For example, if Django retains u'xxx' literals (even though I've ported it using unicode_literals, they may choose a different path officially), users wanting to work with it using 2.6/2.7/3.2/3.3 (as I do now) are SOL as far as a single codebase is concerned. Of course, when you're working on your own project, you can call the shots. But problems can arise if you have to work with an external project, as many of us frequently do. Regards, Vinay Sajip
