Ironically I have weird OCD where I always assume I made a typo, so I keep deleting and retyping code a few dozen character at a type, often in lines where I see nothing wrong. Over time this has just become something my hands do whenever my brain needs time to think about something else. So in a way I developed natural immunity to said unicode tricks ;)
I think you're not alone. A common error I've noticed is when you make a typo somewhere (that compiles) and copy and paste it in a different place where you have the correctly named symbol. It's often hard to see the typo because the eye fly over the word. So you erase and type it manually.
