Subject: Re: utf-8 & Range under eruby (possibly Rails) problems

Someone on PerlMonks taught me a neat trick.   A regex split about
nothing returns an array of one-character strings.  It's true for Ruby
as well ...   So these indexing routines are really simple.

some_string.split(//).each { |c| 
  ...
}

# or ... some_string.split(//)[5]

chars. For the
