In a world where your IDE and maybe also compiler should warn you about using unicode literals in source code, that's not much of a concern.

VSCode (and I'm sure other modern IDEs, but haven't tested) will call out if you're using a Unicode char that could be confused with a source code symbol (e.g. i and ℹ️, which renders in some fonts as a styled lowercase i without color). I'm sure it does the same on the long equals sign.

Any compiler will complain (usually these days with a decent error message) if someone somehow accidentally inserts an invalid Unicode character instead of typing ==.
