U+0305 "̅" Combining Overline Unicode Character

U+0305 "̅" Combining Overline is a diacritical mark designed to be placed over the preceding character, often used to create visual effects like striking through text or indicating mathematical notation such as repeating decimals or line segments. Unlike an underscore or simple line, it combines directly with the base character, allowing it to fit within the vertical space of the font. This combining overline is distinct from the macron, which is shorter and typically placed closer to the letter, and it can be stacked or repeated to form longer continuous lines across multiple characters.
