Lightscription

Do you want to show us what that looks like in assembly, ASCII from machine code? …ha, ha, ha, no!

Depends on the device, I know. Such a pain without the higher level languages.

What would it look like for ARM android touch screens? Just for one character…

But if some characters go missing or are exchanged for others for no discernable reason, then might that be an exploit on a EC or assembly level?

Best still rare even though potentially very user friendly and accessible.
