  Extend class Array and class String to uniformly handle code conversion
  to and from unicode

=end

class String
  
  # Converts a string to an array of unicode values.
  #   'äöü'.to_unicode => [228, 246, 252]
  #   'äöü' as UTF-8 is equivalent to [195, 164, 195, 182, 195, 188]
  def to_unicode
    self.unpack('U*')
  end

end

class Array
  
  # Converts an array of unicodes values to an utf-8 coded string
  #   [228, 246, 252].to_uft8 -> 'äöü'
  
  def to_utf8
		self.pack('U*')
