You might not need them but consider this for a moment: When I was a kid, there was a boy in my class who was mute. He carried a chalkboard and flashcards to facilitate communication. Eventually, he was chosen to pilot a device that was sort of like a keyboard with oversized keys. Each key had a pictograph on it[0]. Wouldn't it be nice for him if the flashcards and keyboard device had a consistent set of characters that were easily recognizable not only by him but by the people with whom he was communicating? Now, would he ever need "MAN IN SUIT LEVITATING"? Probably not (you never know!) but I'm glad there is a standard set of otherwise useful pictographs for people like him. [0] - I'm in my late 20s but this was when few families owned computers, let alone super-helpful handheld devices. Also worth mentioning that this boy knew ASL but attended a regular public school where few students and faculty could so the chalkboard and flashcards were infinitely more practical.
