Out of curiosity, what is the issue? IIRC, the performance depended on how your spelled-it. I believe that is why the spelling got changed in Py3.3.

Not really. It got changed because we have canonical names for the codecs which the stdlib should use rather than rely on aliases. Performance-wise it only makes a difference if you use it in tight loops.

Either way, the code is simpler by just using the default.

... as long as the casual reader knows what the default it :-)

I think it's better to make the choice explicit, if the code relies on a particular non-ASCII encoding. If it doesn't, than the default is fine.
