Unicode Version 17.0

U+31A1 "ㆡ" Bopomofo Letter Zi is an extended phonetic symbol used in the Bopomofo (Zhuyin Fuhao) system, which is primarily employed in Taiwanese Mandarin education and input methods to annotate the pronunciation of Chinese characters. Unlike the standard set of Bopomofo letters that directly correspond to initial consonants or simple vowels, this particular letter represents a specialized or historical sound, often associated with a voiced retroflex affricate or a specific dialectal variant found in certain Minnan or Hakka pronunciations. It is part of the Unicode block for Bopomofo Extended, having been added to support the transcription of sounds not covered by the basic Bopomofo inventory, thereby aiding in the accurate representation of diverse Chinese languages and phonetic nuances in digital text.
