U+01A9 "Ʃ" Latin Capital Letter Esh Unicode Character

Unicode Version 17.0

Ʃ

U+01A9 "Ʃ" Latin Capital Letter Esh is a typographic symbol representing a voiceless postalveolar fricative, the sound of "sh" in English words like "ship" or "shine," and is widely used as a phonetic character in the International Phonetic Alphabet. It is visually similar to a capital "S" but with a longer, descending tail, and its lowercase counterpart is "ʃ". Originating from Latin script adaptations for African languages and phonetic transcription, this character appears in the orthographies of several languages, including some African languages such as Aja and Dagbani, where it serves as a standard letter. Despite its resemblance to the integral sign in mathematics and the Greek letter sigma, it remains a distinct entity within Unicode with specific linguistic and scholarly applications.
