U+31AC "ㆬ" Bopomofo Letter Im Unicode Character

Unicode Version 17.0

U+31AC "ㆬ" Bopomofo Letter Im is a specialized phonetic symbol used in the Bopomofo (Zhuyin Fuhao) system, primarily to represent the sound "im" in certain dialects of Chinese, such as Taiwanese Hokkien or Hakka, where it denotes a final nasal consonant or a complete syllable ending. Unlike the more common Bopomofo letters found in standard Mandarin, this character is part of the Bopomofo Extended block, which was added to Unicode to accommodate additional sounds not covered by the original set. Its inclusion allows for accurate phonetic transcription in linguistic studies and educational materials for these regional languages. The character is visually distinct, resembling a small hook or inverted shape, and is typically used alongside other Bopomofo symbols to annotate pronunciation in reading aids and dictionaries.
