# == String (Patch)
# On ruby 1.9, Strings are aware of multibyte characters, so +size+ and +length+
# give the actual number of characters. In Chef::REST, we need the bytesize
# so we can correctly set the Content-Length headers, but ruby 1.8.6 and lower
# don't define String#bytesize. Monkey patching time!
class String
  unless method_defined?(:bytesize)
    alias :bytesize :size
  end
end

# <= 1.8.6 needs some ord! 
class String
  unless method_defined?(:ord)
    def ord
      self.unpack('c').first
    end
  end
end

Allow to use "a\nb".lines.each syntax in ruby 1.8
