Book and quill crashing game randomly.

Sometimes book and quills crash my game whenever I click through the paragraph or click through the pages too fast. Also, the cursor randomly messes up when I click in the paragraph . It's hard to replicate since it is completely random, but when it did crash it said "invalid characters" This started in 1.14 and since it didn't say it was fixed in the change-log, I assume its still around.
Thanks
