U+1FB6 "ᾶ" Greek Small Letter Alpha with Perispomeni Unicode Character

U+1FB6 "ᾶ" Greek Small Letter Alpha with Perispomeni is a precomposed representation of the Greek lowercase alpha combined with a perispomeni diacritic, which historically indicated a circumflex accent in polytonic Greek orthography. This character is commonly used in ancient and liturgical Greek texts to denote a specific tonal contour on the vowel alpha, often appearing in words where the accent falls on the final syllable or in certain grammatical forms. It belongs to the Greek Extended block of Unicode and is distinct from using a separate combining perispomeni mark, as it simplifies rendering in modern digital systems while preserving traditional typographic conventions.
