The carrot-Z (^Z) representation is how Unix CLI software would display it. Many control codes that didn't actually do anything were printed on the terminals with the carrot prefix. Sometimes codes that did trigger a function in the terminal would be printed that way to prevent the function from triggering. Control-Z is a left over from the CP/M days. It was used to mark the end of text files, since the original file allocation table (FAT) only tracked the number of clusters assigned to a file. Some MS-DOS and MS-Windows applications still tack it on to the end of files. I guess that's their idea of backward compatibility.
