U+0014 "DC4" DEVICE CONTROL FOUR Unicode Character
Unicode Version 17.0
DC4
U+0014 "DC4" DEVICE CONTROL FOUR is a control character from the C0 control code set, originally defined in the ASCII standard to provide a device control function for data transmission. Its primary purpose was to allow a sender to manage remote or peripheral hardware, often meaning it would turn off or deactivate a connected device, complementing other device control codes in the 0x11 to 0x14 range. While largely obsolete in modern text processing, it remains a valid Unicode code point and can be used in legacy systems or specific data communication protocols to signal a device control operation.
