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.

... 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.
