The Amiga was not character-based, it ran an accelerated framebuffer (with support for scanning out multiple resolutions and color depths on a single screen).
Sorry, I was generalizing the "typical" pre-1995 system one would find in commercial installations, which in general were character-based. But I'm sure the Amiga solution would have been nice and fast too, since they were pretty powerful and programmers back then didn't feel the need to bring in PhoneGap, React, or 5,280 npm packages in order to display what amounts to a form.
