U+038C "Ό" Greek Capital Letter Omicron with Tonos Unicode Character
Unicode Version 17.0
Ό
U+038C "Ό" Greek Capital Letter Omicron with Tonos is a precomposed glyph used in modern Greek writing, specifically representing the capital letter omicron (Ο) with a tonos, which is the acute accent mark (Ό) that indicates stress or emphasis in pronunciation. This character is part of the Greek and Coptic block of Unicode and is typically employed in uppercase text, such as at the beginning of words or in all-caps titles, where the tonos must be preserved to maintain correct lexical stress. It should not be confused with the similar-looking Latin letter O with an acute accent, as it belongs to the Greek script and is used exclusively for Greek orthography.
