You can use each_byte to iterate over every character of a string.
Just be aware that it will pass an int character code, not the actual
character itself, into the associated block but you can convert it
back using the chr method like so:
 irb(main):026:0> "hello".each_byte{|c|puts c.chr}
 h
 e
 l
 l
 o
