The use of Empty / Filled board cell would result in the correct metrics and by encoding an empty cell that is different from a "white square", there's no need to overload the use of the latter.

That would not be more legible — quite the opposite, in fact — because it would add variable length to lines for every character in the 8 × 8 matrix in any environment where the ligation failed. That’s not chess-legible.
