U+31A2 "ㆢ" Bopomofo Letter Ji Unicode Character

U+31A2 "ㆢ" Bopomofo Letter Ji is a phonetic symbol used in the Bopomofo system, which is a transliteration and educational tool for Mandarin Chinese pronunciation, particularly in Taiwan where it is often taught alongside or instead of Pinyin. This specific character represents the voiced palatal affricate sound, corresponding to the Pinyin "j" as in "ji," and is part of the extended Bopomofo block that includes letters for dialectal or historical sounds not found in standard Mandarin. It appears in annotations for Taiwanese Hokkien and other Chinese languages, serving as a precise notation for a consonant pronounced by pressing the tongue against the hard palate.
