As I see it, this concerns the kernel and how it handles the data flaw input/output coming from pipes redirection between programs or even from a simple echo/cat command you execute when you're on a tty. By turning that flag "on" (by default is "on") you are telling the kernel it has to expect UTF-8 enconding and my guess is that this setting is aimed to normalize the way console input/output is managed to avoid problems coming from wrong character encoding transformations. > Is the terminal (tty?) driver involved in decoding the input byte stream > into characters for the process attached to the tty device? > > Or does the driver decode bytes into characters only for its own > checking for special characters (e.g., for stty intf CHAR)?
