U+015A "Ś" Latin Capital Letter S with Acute Unicode Character
Unicode Version 17.0
Ś
U+015A "Ś" Latin Capital Letter S with Acute is a grapheme used in several Central and Eastern European languages, including Polish, where it represents a palatalized or soft "sh" sound, as well as in the Sámi languages, Lithuanian, and the transliteration of Sanskrit. It consists of the standard letter S combined with an acute accent diacritic mark above it, placed at Unicode code point U+015A within the Latin Extended-A block. This character is distinct from its lowercase counterpart "ś" (U+015B) and appears in numerous proper names, such as the Polish city "Świnoujście" or the name "Śląsk" for Silesia, reflecting its functional role in linguistic orthography rather than serving as a purely visual variant.
