Spacing for Unicode Block characters is off

Input

SHAPES {
nw ("██") n ("█") ne ("██")
w ("██") e ("██")
sw ("██") s ("█") se ("██")
}

My font has widthxheight ratio of 1x2, so I'd need to block character for a square block.

The output is:

echo "boxes" | boxes
███████
██         ██
██  boxes  ██
██         ██
███████

This is on Linux in the foot terminal, with fish shell. But it occurs similarly in other terminals and shells.
Boxes 2.1.1

In foot/fish

In kitty/bash

It must be something with unicode-encoding and spaces and tabs, but I can't seem to get it working. I really like the idea of this program, so I'd like to help out to get it working, but this is as far as I could get on my own.

if I double the characters in N and S, then it would just push the East border even further:

Right, the config file is currently ASCII. We aim to change this, but it's a lot of work, see #72.
