U+2017 "‗" Double Low Line Unicode Character
Unicode Version 17.0
‗
U+2017 "‗" Double Low Line is a typographic symbol that represents two low horizontal lines positioned one above the other, similar to the underscore but reproduced twice. Unlike the standard underscore or combining macron below, this character is a distinct code point used in legacy character sets and specific linguistic applications, such as representing a distinct tone or placeholder in certain phonetic or textual systems. It is also occasionally employed in decorative or separative contexts within plain text, though it is less common in modern digital writing due to the availability of combining diacritics and other formatting options.
