It's a cultural tic to refer to something by its name.
You should check the actual manual: http://applelogic.org/files/AIIEREF.pdf
First, the cover uses italic sans-serif “I” characters, not forward slashes. It’s pretty clear if you’re familiar with typography.
Second, the body of the document uses neither. It uses the standard upright I character.
Is it it's name tho? Legally and culturally, do they have the power to name it?
*its
I mean, like you want to name your dog Bell character, right-to-left character, Bell character, 0-width space. Can you do that legally? Can you do that culturally? Would that become the dog's name in most of the senses?
Random characters in Apple product names is similar territory, although less extreme.
