Any one who has spent any time creating content for PG knows that it IS NOT as simple as “displaying the exact same words in the same order.”

Only “trivial” books follow this rule, and even then it is extremely hard to find a book so “trivial” that accurately representing what the author intended simply requires one to “display the exact same words in the same order.”

There are counter-examples everywhere going back 100s of years from the very start of printing presses which demonstrate books ARE NOT simply “a list of words in the same order.”  Which is why from the very start of printing various fonts and font variations and sizes have been used, and various “tricks” of typography have been used NOT simply “listing words in order” – in order to correctly display *the intent* of the author where simple linear ordering of words *is simply not sufficient!*
