That's because gdb uses libreadline (or something along those lines) with cbreak, so it can intercept control characters without them getting interpreted by the terminal. This requires manual control of terminal functions, which is something outside the scope of readf(). (You'd be better off writing your own terminal handling from scratch, if that's what you want.)
