Use Enumarators:
================================
irb(main):001:0> str = "ÄÄÄÖÖÖÜÜÜ"
=> "ÄÄÄÖÖÖÜÜÜ"
irb(main):002:0> str.chars.each_slice(3){|x| p x}
["Ä", "Ä", "Ä"]
["Ö", "Ö", "Ö"]
["Ü", "Ü", "Ü"]
=> nil
irb(main):003:0> str.bytes.each_slice(3){|x| p x}
[195, 132, 195]
[132, 195, 132]
[195, 150, 195]
[150, 195, 150]
[195, 156, 195]
[156, 195, 156]
=> nil
irb(main):004:0>
================================
