Even though the OP seems offended by the presence of the Unicode quote marks for some reason, they have nothing to do with the issue of Apple Books surrounding the copied text with those quote marks and adding an attribution line. If they'd surrounded the text with ASCII quote marks and added an attribution line, it would have still been a syntax error, wouldn't it.

Personally, I don't see any reason to hate typographically correct quote marks when used correctly, which (obviously) doesn't include code samples.
