@HarryT,

I do have a another question regarding digits 0-9 contained in the main text content.

Originally I left all digits unscrambled.
Pros - less confusion when clicking footnote hyperlinks and numeric TOC entries would match their numeric heading/footnote 'other end'.
Cons - copyright page would contain unscrambled ISBNs - which may be a dealbreaker

If digits need to be scrambled, which of the following would be most acceptable. Replace each digit with:

1. a random digit (1 in 10 chance of not being scrambled)
2. a digit guaranteed to be different from the correct one
3. use a single digit everywhere, e.g. all digits displayed as zero
4. replace all digits with a random alpha A-Z char
5. something else I haven't thought of
