The Icelandic alphabet differs from the English alphabet in several ways. First, there is no c, w, or z. But they still have a pizza (pitsa, flatbaka) chain called Pizzan.is. Then they have lots of accented letters which they consider separate letters. These are only on the vowels. Finally, they have two letters that are uniquely Icelandic: þ and ð. These both have th-like sounds.
