U+01BC "Ƽ" Latin Capital Letter Tone Five Unicode Character
U+01BC "Ƽ" Latin Capital Letter Tone Five is a rarely used Latin letter that was historically employed in the phonetic transcription of certain African languages, particularly in the context of the International Phonetic Alphabet (IPA) to represent a specific high or extra-high tone, often denoted as tone five in a language's tonal system such as those found in the Zhuang language or other tonal languages of Africa and Asia. Its uppercase form is visually a reversed and modified letter C, designed to pair with its lowercase counterpart U+01BD "ƽ", and it belongs to the Unicode block Latin Extended-B, though it sees virtually no use in modern standardized orthographies and has largely been supplanted by other tone marking systems like diacritical marks or numeric superscripts.
