U+1E64 "Ṥ" Latin Capital Letter S with Acute and Dot Above Unicode Character

U+1E64 "Ṥ" Latin Capital Letter S with Acute and Dot Above is a composite glyph used primarily in certain Latin-based orthographies, most notably in the transliteration of Indic scripts or in the writing of African languages where phonological distinctions require marking stress or tone with the acute accent and a separate diacritic dot above. It represents a voiceless alveolar sibilant sound, with the acute mark indicating a specific tonal or stress pattern distinct from plain "S" or other modified forms. This character is encoded in Unicode as part of the Latin Extended Additional block, ensuring proper rendering in digital text when a language or scholarly system demands this precise combination of diacritics for accurate phonetic representation.
