U+0090 "DCS" DEVICE CONTROL STRING Unicode Character

U+0090 "DCS" DEVICE CONTROL STRING is a control character defined in the C1 control code set, used in text communication protocols to delimit a sequence of data intended for a specific peripheral device, such as a printer or terminal. Unlike printable characters, it does not represent a visible glyph but instead signals the start of a structured control string that can carry commands or data for device configuration. This character is part of the legacy ISO/IEC 6429 standard and is rarely used in modern plain text, though it may appear in certain terminal emulation or data stream contexts.
