I should add that the odd symbol does not appear within the Calibre interface in the comment section for any book.

5mb equals about four reloads of a regular online newspaper front page, but I understand that you might not want to share your catalog

Anyway, try deleting a few of the characters "surrounding" the position of the question mark, and type them again. For instance the bolded characters here:

"...second edition was edited by her sister Charlotte.�

The name of the novel comes..."

If that doesn't help, maybe you could create a new library and copy only this book there, and make a tiny catalog to upload?
