box = constants that identify a box drawing entity.
1&2 = v, V, u, U, d, D, Ud, or uD, as follows:
v = vertical line for full height.
u = upper half of vertical line.
d = downward (lower) half of vertical line.
3&4 = h, H, l, L, r, R, Lr, or lR, as follows:
h = horizontal line for full width.
l = left half of horizontal line.
r = right half of horizontal line.
In all cases, an upper-case letter means a double or heavy line.
