My apologies, I just got what you meant! How's this?

 celtic@sohma:~$ cat test.rb
class String
  def to_binary
    self.unpack('c*').map {|x| x.to_s(2).rjust(8, '0')}.join
  end

  def self.from_binary b
    b.scan(/.{8}/).map {|x| x.to_i(2)}.pack('c*')
  end
end

string = "Hello, world!"
puts binary = string.to_binary
puts String.from_binary(binary)

celtic@sohma:~$ ruby test.rb
01001000011001010110110001101100011011110010110000100000011101110110111101110010011011000110010000100001
Hello, world!
celtic@sohma:~$

HTH,
Arlen.
