As this link shown, Jest uses a square root mark \u221A on Windows as icon, not the real check mark \u2713. The former will display more like a √ ̅ ̅ style on some font like Fira Code.
But why does Jest do that, is there some unicode issue on Windows, I can use console.log("\u2713") to get a correct check mark on Chrome 96.0.4664.45, Windows 19044.1348
