Yes, this. Though I prefer the X11 compose sequence business where you type <Compose>'a to get á and so on. X11 compose sequences are a lot more intuitive than the Windows U.S. international keyboard because there's no ambiguities, so, for example, a cedille is just <Compose>,c whereas in the Windows U.S. international keyboard layout it's 'c -- X11 for the win here, as the latter is super a) counter-intuitive and b) conflicts with ć (U+0107).

Also, if you program or use a shell, then the Windows U.S. international keyboard layout is just unspeakably unbearable.
