In addition to manually using Integer.chr, you may find Array.pack
useful:

esau:~$ irb
irb(main):001:0> 'asdf'.unpack('c*')
=> [97, 115, 100, 102]
irb(main):002:0> [97, 115, 100, 102].pack('c*')
=> "asdf"

s=%q(  Daniel Martin -- martin@snowplow.org
       puts "s=%q(#{s})",s.to_a.last       )
       puts "s=%q(#{s})",s.to_a.last
