Sure. I don't know what most of the buttons do on my car's dashboard, because of the "iconitis" disease that has infected user interface design. Unicode has blessed and encouraged this crap. They don't just standardize, they invent icons intending them to replace the phonetic words.
(Apple is kinda schizophrenic on this. Sometimes you'll see "DELETE" as a button, sometimes a trash can.)
I don't know what the wash icons on my clothes mean without going to google and looking them up.
You can't look up an icon in a dictionary, making it a fundamentally wretched replacement for a phonetic alphabet. Worse, people persistently try to invent icons for verbs and adjectives, which never ever work. Even for nouns, is that scribble a bird, a duck, or a chicken?
My car has a button with something that looks like a snowflake on it. Does it turn the heater on? The defroster? The air conditioner? Turn on traction control? Who the hell knows?
