U+01A7 "Ƨ" Latin Capital Letter Tone Two Unicode Character

U+01A7 "Ƨ" Latin Capital Letter Tone Two is a typographic symbol used primarily in certain African languages, particularly in the orthography of languages like Mbelime and some other languages of Benin and Togo, where it represents a specific tone, often a mid or falling tone, in tonal writing systems. Its lowercase counterpart is U+01A8 "ƨ", and it visually resembles the digit 2 turned upside down, which reflects its historical origin as a simplified adaptation for distinguishing tonal marks in contexts where standard diacritics were impractical. This character is distinct from the upside-down "S" used in other scripts or as a decorative glyph, and it is encoded in the Latin Extended-B block of Unicode to support the accurate digital representation of these tonal languages.
