U+2381 "⎁" Continuous Underline Symbol Unicode Character

Unicode Version 17.0

U+2381 "⎁" Continuous Underline Symbol is a graphic character defined within the Miscellaneous Technical block, representing a continuous horizontal line intended for use in terminal or text interface applications to denote an underline that spans across characters or spaces without breaks. Unlike the standard underscore character, which is a single glyph, this symbol is designed as a formatting or control indicator in systems like APL (A Programming Language), where it may be used to apply a sustained underline to a sequence of text. It appears as a short, solid line and is part of a set of symbols that include the broken underline (U+2380) and other editing marks, providing precise visual cues for text processing or user interface design.
