Unicode Version 17.0
𐅦
U+10166 "𐅦" Greek Acrophonic Troezenian Fifty is a numeral symbol from the ancient Greek acrophonic numbering system used specifically in the city-state of Troezen, where it represented the value of fifty. This character belongs to the Ancient Greek Numbers block of the Unicode standard and is based on the initial letter of the Greek word for fifty, much like other acrophonic numerals. Its design typically resembles a stylized form of the letter Pi, reflecting the boeotian or local variation of this counting system that predated the later, more widespread Attic numerals. The inclusion of this character preserves a snippet of ancient Greek epigraphical and arithmetical practice for modern digital use.
