U+31B0 "ㆰ" Bopomofo Letter Am Unicode Character

Unicode Version 17.0

U+31B0 "ㆰ" Bopomofo Letter Am is a phonetic symbol used in the Bopomofo system, also known as Zhuyin Fuhao, which is a phonetic notation system primarily employed in Taiwan to transcribe Mandarin Chinese and other Sinitic languages. This particular character represents the sound "am," which is a nasal consonant-vowel combination, and it is part of an extension of the standard Bopomofo set used more broadly for writing additional Chinese dialects or languages beyond standard Mandarin, such as Hokkien or Hakka. The character is encoded in the Unicode Bopomofo Extended block, which was added to support these expanded phonetic needs, and it appears as a small, stylized glyph that visually combines an umbrella-like top stroke over a straight vertical line.
