This scenario could be extended to just about any symbol(s) imaginable.
Page 10 of the Colorado Driver Handbook shows the well-known graphic of
a glass of wine, a shot of whiskey, and a pilsner glass full of beer to
drive home the point that they contain the same amount of ethanol. If
those were encoded as characters, the graphic could be dispensed with.
There are also numerous images of traffic signs and text referring to
them. And so on.
