*All* these alpha-numeric characters can easily fit on one screen if
you switch a Unicode/ASCII encoding by tapping [Tab], perhaps in
Fullscreen mode for larger sizes. I do not see much need for such
interactive mode. Also. `ftview` adds a pixel in-between so what you
see is not exactly a layed out text. This might belong to `ftstring`
with proper layout, but I doubt if it can be implemented for non-Latin
scripts.
