U+0012 "DC2" DEVICE CONTROL TWO Unicode Character

U+0012 "DC2" DEVICE CONTROL TWO is a control character from the C0 control code set, originally defined in ASCII as a communication protocol command. Its primary historical function was to allow a sender to remotely manage a peripheral device, typically a printer or terminal, by activating a specific device or feature, distinct from other device control codes like DC1. In modern computing, U+0012 is rarely used in user-facing text, as it lacks a visible glyph and instead serves as an invisible delimiter within data streams or legacy systems.
