I might not be following your train of thought correctly , but what I think you are wanting to accomplish is done by what you weed ... instead of weeding what you normally would ... weed the letters . Make a 8 X 3 box around the letters . I think an outline looks much better than a square box .
edit ; you want to negative weed , instead of cut anything negative . My buds FouASH ( Ash ) & Bay ( Bayotle ) have had the same problem mutiple times ... I tell them "I can explain it to you over and over, but I can't understand it for you."
