U+203E "‾" Overline Unicode Character
Unicode Version 17.0
‾
U+203E "‾" Overline is a typographic symbol that represents a horizontal line placed above text, primarily used to indicate a continuous line over a sequence of characters, often serving as a diacritical mark in certain transliteration systems or as a formatting element in plain text environments where underlining is not available. It differs from the macron U+00AF, which is a dedicated combining diacritic, because the overline is a distinct spacing character meant to span multiple characters in contexts like fractions (e.g., 1‾3) or to denote nonbreaking spaces in text processing, and it is also employed in computing as a visual placeholder for missing or hidden data.
