Cham Digit Five at U+AA55 represents the number five in the traditional numeral set of the Cham script. It belongs to the Cham Unicode block, which covers characters used for writing Cham languages and related manuscript traditions of mainland and maritime Southeast Asia. In practice, this digit is used where text is set fully in Cham script and the numbering is kept in the same script style. It can mark quantities, dates, verse or page numbers, lesson exercises, and numbered lists in Cham-language educational materials, religious texts, linguistic records, and digitized manuscripts. Its modern use is specialized rather than everyday, because many Cham publications and keyboards may use ordinary Western digits instead. The character matters most for faithful transcription, font testing, cultural publishing, and search in archives where a Cham numeral five must remain distinct from the ASCII digit 5.
