As Akira Tanaka and myself have already said, please provide
examples of actual code and actual performance figures, so that
we can look at the details.

Separating out implementations for different encodings is already
done at the very basic level, and the overhead for the dispatch
needed to figure out which encoding is being used is about the
same as the overhead of the general Ruby method dispatch, which
we have anyway, and with high probability won't buy much.
