I've used other symbols in a conventional manner (e.g., ^ for "this
end up").

 Just a small point:  The legend "This Side Up" is pointless on the top
side but "Other Side Up" on the bottom side is far more useful.

Text is eschewed because it is monolingual AND hard to read
without eyesight.
A symbol can be seen or felt to identify it's general characteristics.
(Imagine "feeling" the traditional barrel connector polarity identifiers;
how large would they have to be for you to be able to discern their
intent?  Now, imagine having neuropathy diminish the sensitivity in
your fingertips...)
