U+1E68 "Ṩ" Latin Capital Letter S with Dot Below and Dot Above Unicode Character
U+1E68 "Ṩ" Latin Capital Letter S with Dot Below and Dot Above is a specialized variant of the Latin letter S used primarily in African linguistic orthographies and phonetic transcription systems. This grapheme combines a base uppercase S with two diacritical marks a dot placed beneath the letter and a dot placed above it, which serve to indicate a specific phonemic distinction, often representing a retroflex or palatalized fricative sound in languages such as the Vai script of Liberia or in standardized alphabets for some Central African languages. Its inclusion in Unicode ensures that digital text can accurately represent these phonetic nuances without requiring fallback characters, making it essential for precise documentation and communication in linguistics and minority language preservation.
