U+2413 "␓" Symbol for Device Control Three Unicode Character

U+2413 "␓" Symbol for Device Control Three is a graphical representation used in the context of data transmission and computer standards to indicate the Device Control Three (DC3) control code, which is part of the C0 control code set in the ASCII standard. Historically, this control character, with a decimal value of 19 (often referred to as XOFF in software flow control), was employed to signal a device, such as a printer or terminal, to pause or cease data transmission temporarily, typically during handshaking or flow control procedures. The graphic symbol itself was designed to be displayed in place of the invisible control code when viewing or editing raw data, making it a visual placeholder rather than a functional character in modern systems.
