U+0331 "̱" Combining Macron Below Unicode Character
Unicode Version 17.0
̱
U+0331 "̱" Combining Macron Below is a combining diacritical mark used in written text to be placed directly underneath a preceding base character, where it creates a visual line or bar under that letter. This mark is most commonly employed in linguistic transcriptions, such as in the International Phonetic Alphabet, to indicate a specific phonetic quality like a lowered or retracted articulation, and it is also used in certain romanization systems for languages like Arabic and Sanskrit. Because it is a combining character, it does not have an independent width or appearance on its own but instead modifies the glyph it follows, ensuring that the macron is correctly aligned beneath the base letter.
