安佐 is a phonetic transliteration most often used for the Italian given name Enzo or for Anglicized 'Anzo'.
安 ('peace') is the go-to character for foreign names starting with An-/En-, and
佐 ('to assist') captures the closing '-zo'. Famous bearers: Enzo Ferrari (
恩佐·
法拉利) — note he gets
恩佐, not
安佐, because Italian pronunciation is closer to 'En-' than 'An-'.
