U+31B5 "ㆵ" Bopomofo Final Letter T Unicode Character

U+31B5 "ㆵ" Bopomofo Final Letter T is a rarely used phonetic symbol from the extended Bopomofo block, designed to represent the final consonant "t" sound in certain Chinese dialects or phonetic transcriptions. Unlike standard Bopomofo letters which primarily indicate initial consonants or vowels, this character functions specifically as a closing sound, similar to the unreleased final "t" found in languages like Cantonese or other southern Chinese varieties. It was added to Unicode as part of a collection of supplementary phonetic notations, allowing for more precise representation of sounds not covered by the basic Bopomofo set. Though not commonly seen in everyday Mandarin materials, it remains important for linguistic research and specialized dictionaries that document historical or regional pronunciations.
