^D normally closes the input when you are in cooked mode, but to be
able to read chars one by one you cannot use this mode
read set the terminal mode to cbreak or raw mode ^D stops to be
special and "read"  reads your ^D
if you try with "read -n2" you'll notice that you have to press it
twice and the replies contains 2 control d:
$ read -n 2
^D^D$ printf %q "$REPLY"
$'\004\004'$
