The main difference I saw was that a character would be
represented as String rather than a Fixnum.  I'd rather see it
remain an Integer to handle the unicode encodings - Fixnum when
that is enough and Bignum where needed.  That would give better
compatibility.  And efficiency when dealing with encodings that
fit in a Fixnum.

I'm not quite sure, but with this change, I think my stuff
would still be fine.  You'd just have to think of a String as
an Array of Strings instead of an Array of Fixnums.

I just hope the common set of methods between Array and String
don't get smaller.
