U+1E63 "ṣ" Latin Small Letter S with Dot Below Unicode Character

U+1E63 "ṣ" Latin Small Letter S with Dot Below is a specialized letter used primarily in transliteration systems for languages such as Sanskrit and other Indic scripts, where it represents a retroflex or cerebral sibilant sound, distinct from the standard English "s". It also appears in the orthographies of several African languages, including Hausa and Oromo, as well as in historical or scholarly transcriptions of Semitic languages like Arabic and Hebrew. The dot below serves as a diacritical mark that modifies the base Latin letter "s" to indicate a specific phonetic value, often a voiceless retroflex fricative, and it is encoded in the Unicode standard under the category of Latin Extended Additional to support precise textual representation in digital environments.
