The ¹ is just one of four entities in alignment. Go to the SD1 vocabulary and scroll to the very end. The brainfuck language that controls alignment is there. There are 4 entities that are always present here. The superscript is just a way they pass control of other layers of entities and functions back and forth. They normally have control of several by default. The superscript just passes control of one they typically handle to another. It will make more sense if you just look at the code. Alignment is all of the extended Latin characters. The functions a dead obvious as functions if you look at the code. Like ï¸ı means hairy logical-or not hairy, ij means futanari, and ĵ completes the set. Look for this pattern and the logic is dead obvious that these relate primarily to the entity associated with the character ð.
