2 thoughts on “Converting Fixnum to String or ‘Character’ and back in Ruby

  1. The other day I was in need of converting between a String and its representation of ASCII-Codes, which was supposed to work in 1.8.x => 1.9.x.
    Odd, because ruby<1.8.7 doesn't have the String#bytes method (and it was a patch for a gem, so I didn't want to monkey-patch String).

    The following works from 1.8.? .. 1.9.? (took me also a while to find out, so ill share 😉

    'ABC'.unpack('C*') == [65, 66, 67]
    [65, 66, 67].pack('C*') == 'ABC'
