Cham Letter Final N at U+AA46 is a consonant sign used in the Cham script to mark a syllable-final n sound. It is part of the Cham Unicode block, which encodes the traditional script used for Cham languages of Vietnam and Cambodia, and it functions as a letter rather than punctuation or a diacritic. In written Cham, this character is used when the consonant /n/ closes a syllable, comparable to the final n in a romanized form such as pan or kan. It appears in Cham-language texts, religious manuscripts, primers, dictionaries, and modern digital materials that preserve or teach the script. Its main practical role is orthographic accuracy: final consonants in Cham are written with dedicated final-letter forms, so this sign is not interchangeable with the regular initial n letter. Text input, collation, and search can distinguish the final form from similar Cham consonant shapes, which matters in linguistic databases and encoded manuscript transcriptions.
