Because it only makes sense on a string of (character) length one.

Because that's complicating matters unnecessarily, and indexing
shouldn't be part of the interface to a method that turns a string
into its position in the encoding table of the string in question.
You wouldn't expect String#succ to take an index, or String#hex for
that matter, right?
