I wasted 40 minutes trying to understand what do they mean in the calculus textbook with this notation.
Turns out, after quitting the Preivew app and opening the book again, that this was some loading issue of the pdf, and once loaded properly, these symbols (large bold 1 or 2 with a following "bar" or "roof") are square root symbols.
For context if useful: the book is hosted in my Books app on iCloud, I am at a train with fairly bad internet.
Why does it happen, will it be fixed?

I might suspect a connection issue is the culprit(?) Get on a faster internet to compare your results and report back.
It would be impossible for me to try an duplicate the exact circumstances.
You would suspect the font data must be embedded within the PDF file at the time it is created. This makes the PDF self-contained and ensures that anyone can view it as intended, even offline(?) but I can not really speculate further.
