This font has all 83 possible combinations if pixels based on a 3x3 grid and that all pixels are connected including any that have mirror images mirror images are only counted once.   this is the culmination of much work, there have been maybe one  or two symbols I pulled out as they were too similiar  to others, namely the lines these symbols are as  such that they can be read in any direction they would read the same  in other words any symbol that is rotationally the same is the same symbol in this set...assuming you rotate in 90 degrees increments.

Added one more symbol = two parallel lines so this totals 84 patterns
