Hey! Dont try and mandela effect sanctuary moon into existence, you almost had me.

Could be wrong, but that wont deadlock because 5 seconds later, you're going to have call/2 fail.

The corners of the boxes appear in the wrong place in the cell.

I don't think there is utf8 characters that allow for drawing on the outside of the cell, (happy to be wrong)

┌ (U+250C), ┐ (U+2510), └ (U+2514), ┘ (U+2518) <-- these 4 draw in the middle of the cell.

｢ (U+FF62), ⌟, (U+231F), <-- these are two that cover part of the outside, but not the other corners.

｢┐└｣

Can anyone tells me how to get those 'corner of cell' characters, including uprights and horizontals ?

Its almost like they are sick of people commiting crimes.

You're right. Justice should be served with reason and justice, at the moment it is served with far too much compassion for the criminal.
