U+31A8 "ㆨ" Bopomofo Letter Ir Unicode Character

Unicode Version 17.0

U+31A8 "ㆨ" Bopomofo Letter Ir is a lesser used phonetic symbol within the Bopomofo system, also known as Zhuyin Fuhao, which is utilized in Taiwan for teaching Mandarin Chinese pronunciation and transcribing sounds. This specific character represents a rare or dialectal vowel sound, often described as a close central unrounded vowel, and is not commonly found in standard Mandarin phonetics. It appears in the Unicode Bopomofo Extended block, having been added to accommodate the transcription of certain minority languages or variant pronunciations that require a finer distinction than standard Bopomofo letters provide. As a result, its primary role is in specialized linguistic documentation rather than everyday language learning.
