A while back I used these kinds of characters to encode programs into invisible text: https://www.thelisowe.com/sleeper-cell-a-method-of-embedding...

It doesn't do much on its own. I feel like it could, but the most effective use case I've come up with it you can invisibly plant a piece of code in some piece of text, then later on run another script that looks for that piece of code and runs it. I'm guessing that splitting the code up like this would make it harder to detect (not to mention that this code could even reside in other programs' comments undetected).

I’ve seen it as a Bacon code in capture-the-flag.
