U+1AFF9 "𚿹" Katakana Letter Minnan Nasalized Tone-3 Unicode Character

U+1AFF9 "𚿹" Katakana Letter Minnan Nasalized Tone-3 is a specialized typographic symbol used in linguistic and phonetic transcriptions of the Minnan (Southern Min) language, particularly to denote a nasalized version of the third tone. Belonging to the Katakana Phonetic Extensions block, this character was added to the Unicode standard to support accurate representation of certain Southern Min dialects where tone and nasality are critical for meaning. Its design resembles a modified katakana character, serving as a precise diacritic-like mark in written phonetic notation rather than as a standard Japanese kana.
