U+1FDD "῝" Greek Dasia and Varia Unicode Character

U+1FDD "῝" Greek Dasia and Varia is a combining diacritical mark used in polytonic Greek orthography to represent a specific breath and accent pattern on a vowel or a rho. It combines the dasia (rough breathing) which indicates an initial "h" sound with the varia (grave accent) which indicates a lower or falling pitch. This character is typically placed over the initial letter of a word that begins with a vowel or a rho, signaling both the aspiration and a particular tonal quality in ancient Greek pronunciation. It is distinct from other combining combinations like the dasia and oxia, as the varia accent modifies the syllable's tone differently.
