U+009D "OSC" OPERATING SYSTEM COMMAND Unicode Character

U+009D "OSC" OPERATING SYSTEM COMMAND is part of the C1 control character set, originally defined for use in terminal and text communication protocols, particularly within the ANSI escape code sequences common in VT100 and similar terminal emulators. It serves as the start of an Operating System Command sequence, which instructs the terminal or receiving application to perform a system level action such as setting the window title, manipulating the clipboard, or changing the current working directory, with the command parameters following until the string terminator (typically BELL or ST) is sent. While not intended for general text display, this control character remains supported in many modern terminal environments for backward compatibility.
