Found something funny when reading Tailscale code. They use a Cyrillic letter "ж" (reads as "zh") for the variable which shouldn't be exposed to callers and mutated. This is an artificial barrier for human devs that should raise concerns when trying to type it. Apparently it looks like an asterisk meaning it's a pointer. But for me it's a familiar letter which I didn't expect to see in the code and was like Ж? WAT? Yeah, you can use unicode letters in Go code if you want. I now really want to use something like that in my code because I bet it'll make me smile every time I see it
