U+311B "ㄛ" Bopomofo Letter O is a phonetic component used in the Bopomofo (or Zhuyin Fuhao) system, a Chinese character pronunciation guide primarily employed in Taiwan for teaching Mandarin. This character represents the sound of a close-mid back rounded vowel, similar to the "o" in English words like "go," and it is typically used as a standalone final or combined with other Bopomofo symbols to form syllables.
