U+23BB "⎻" Horizontal Scan Line-3 Unicode Character

U+23BB "⎻" Horizontal Scan Line-3 is a graphic symbol included in the Miscellaneous Technical block, designed to represent a horizontal scanning line in visual display or raster graphics contexts. Its name specifically indicates it is the third variant in a series of horizontal line characters, often used in technical diagrams or schematic depictions of cathode ray tube (CRT) scanning patterns. While not commonly seen in everyday text, this character supports the representation of legacy monitor scan lines and can also appear in certain block-element illustrations for low-resolution display effects.
