Display characters on a square grid?

Question

How can I display characters as if they are square in vim? The characters themselves don't need to be square, but if you were to draw a grid through all centre points of the characters it should make a square grid.

I would like to do this because I am designing a fortress layout for Dwarf Fortress. The game is set out on a square/cube grid.

Create a square mono-spaced font from Courier using your favourite font-editor. Use that in your Terminal.

If you lack the patience for font editing and have charisma (or something) you can do this instead.

The intertubes suggested this to me but maybe it isn't really square.
