A decision had to be made on how to split up a string when using each. The
decision was made to split it up by lines, since that was deemed to be the
most often used case. I think that's probably a correct assessment. Now, if
you want it to use something other than newlines as its split, you can
explicitly split by whatever you want:

'foobar'.split('').each { |c| puts c }

Basically, stringvar.each is a shortcut for stringvar.split("\n").each
because line splitting is the common case.
