U+1FBB "Ά" Greek Capital Letter Alpha with Oxia Unicode Character
Unicode Version 17.0
Ά
U+1FBB "Ά" Greek Capital Letter Alpha with Oxia is a precomposed character used in polytonic Greek orthography, representing the uppercase alpha combined with the oxia diacritical mark, which historically indicated a high pitch accent or, in modern usage, denotes stress. This character is part of the Greek Extended block and is typically employed in classical texts, liturgical writings, or scholarly editions where accentuation is preserved, though in contemporary Greek it has largely been replaced by the simpler uppercase alpha with a tonos (U+0386). Its design visually combines the standard Greek capital alpha with a sharp, right-leaning stroke above the letter.
