This is the opposite of Prevent “^C” from being printed when aborting editing current prompt.

I'm using Bash. When I'm editing the commandline in Bash, and I hit Control-C to abort the commandline, the '^C' character does not display. I would like to see this character.

I tried commands like stty -ctlecho and stty ctlecho (which I borrowed from the other question), but this didn't work for me. This behavior seems to be true with my environment on Ubuntu, CentOS and MacOSX. This only happens within Apple's Terminal.App. If I SSH to a remote Linux or FreeBSD box, then ^C is printed. So, this is clearly just a local setting.

Update:

Here is the output of stty -a, as requested by @quack quixote :

$ stty -a
speed 9600 baud; 41 rows; 88 columns;
lflags: icanon isig iexten echo echoe -echok echoke -echonl echoctl
 -echoprt -altwerase -noflsh -tostop -flusho pendin -nokerninfo
 -extproc
iflags: -istrip icrnl -inlcr -igncr ixon -ixoff ixany imaxbel iutf8
 -ignbrk brkint -inpck -ignpar -parmrk
oflags: opost onlcr -oxtabs -onocr -onlret
cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow
 -dtrflow -mdmbuf
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
 eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V;
 min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T;
 stop = ^S; susp = ^Z; time = 0; werase = ^W;

After typing stty sane, stty -a will output the following. The only difference is the parameter of -iutf8.

$ stty sane
$ stty -a
speed 9600 baud; 41 rows; 157 columns;
lflags: icanon isig iexten echo echoe -echok echoke -echonl echoctl
    -echoprt -altwerase -noflsh -tostop -flusho pendin -nokerninfo
    -extproc
iflags: -istrip icrnl -inlcr -igncr ixon -ixoff ixany imaxbel -iutf8
    -ignbrk brkint -inpck -ignpar -parmrk
oflags: opost onlcr -oxtabs -onocr -onlret
cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow
    -dtrflow -mdmbuf
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
    eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V;
    min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T;
    stop = ^S; susp = ^Z; time = 0; werase = ^W;
