U+1FFE "῾" Greek Dasia Unicode Character
Unicode Version 17.0
῾
U+1FFE "῾" Greek Dasia is a diacritical mark used in polytonic Greek orthography, historically known as the "rough breathing" sign. It indicates that a vowel or the letter rho at the beginning of a word should be pronounced with an aspirated or "h" sound, similar to the English "h" in "house." Unlike the smooth breathing mark, which denotes no aspiration, the Dasia appears as a right-facing comma-like symbol placed above the initial vowel or on the first element of a diphthong, and it is essential for accurately reading and interpreting ancient and liturgical Greek texts.
