Text formatted with § (section sign/paragraph symbol) can escape page on a Book and Quill

When pasting special text into a book, the text can fall off the page

Steps to reproduce:

Paste the section symbol into the book (§)

Append the text "l!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

Paste in the section symbol again

Append the text "r!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

The text will go outside the page boundary, and will still be bold even though the formatting was reset with §r
