Yeah possibly.  Another problem with each_byte is that byte != char for
many encodings.  But AFAIK #each_byte and #split(//) share this problem.

I believe a drawback of using "foo".split(//) is that it's less
performant: you need to create the tmp array plus all the string instances
(although they share the buffer AFAIK).
