Kent, I believe the box drawing characters are for drawing boxes and grids on computer terminals, which is not the same thing as scoring a line around a set of 64 graphic images. I don’t want to get mixed up in using the box-drawing characters. The characters which I have chosen work fine and to my mind suit the application better.
I also don’t want to complicate chess fonts by having to have multiple choices within a font for bordering. For one thing, single-rule and double-rule bordering is by no means the gamut of possibility. Chess fonts do not have to be swiss-army knives. Thank you for your consideration, but I will stick with using the ⅛-block and quadrant characters.
