U+1FEC "Ῥ" Greek Capital Letter Rho with Dasia Unicode Character

U+1FEC "Ῥ" Greek Capital Letter Rho with Dasia is a historical Greek symbol representing the letter Rho combined with a dasia, which is a diacritical mark indicating rough breathing or an initial aspiration sound, similar to an "h" in English. This character is primarily used in ancient Greek texts and scholarly works to transcribe words where a capital rho word initially required aspiration, such as in Ῥωμαῖος (Rhōmaios, meaning Roman). It is encoded in Unicode to support accurate digital representation of polytonic Greek script, which preserves the nuanced pronunciation and orthographic conventions of classical and medieval Greek literature.
