Made this version of Bop Carre a while ago, but kept it in the drawer since the letterspacing trick didn't work back than. I started my characters one grid square left from the origin to make them stick together. Worked in the structing window, not in the truetype.
But: halelujah! those wonderful people behind FontStruct fixed this so here we are: Bop as it should be: cosy & close.
One tricky thing though: I also used the advanced features to create the gaps between the blocks in each character. And see: in the truetype version there are gaps between the blocks within each character, but not between two adjacent characters That is easily solved by adding a tracking of +10 in Indesign.
