U+0384 "΄" Greek Tonos Unicode Character

U+0384 "΄" Greek Tonos is a combining diacritical mark used in modern Greek writing, primarily placed above a vowel to indicate stressed syllables as part of the monotonic accentuation system adopted in 1982. It resembles a small acute accent or apostrophe and is distinct from the ancient Greek polytonic accents such as the oxia or varia. In Unicode encoding, this character serves as a spacing and non spacing mark that can combine with base Greek letters, though in practice it is often replaced by the similar looking U+00B4 acute accent or the U+1FFD oxia due to historical and typographical conventions. The tonos is essential for correct pronunciation and meaning in Greek, as stress placement can differentiate words, such as in the verb "γράφω" (I write) versus the noun "γραφή" (writing).
