[REQUEST] Using unicode check mark instead of square root.

I notices in the loading screen, square roots are being used for check marks. Unicode U+1F5F8 is an actual check mark character so can you please use this instead of the square roots?

Start at the loading screen implementation and search for the square-root characters used as check marks. Replace the relevant characters with Unicode U+1F5F8, then verify that the loading screen displays the intended check mark correctly in the terminal.
