Issue Description

I am trying to change the text of a book into Runelic or Pigpen , but nothing changes other than the items name.

Thanks for reporting this. I've released 23.0.6 which fixes this issue. The file is currently being processed by CurseForge so it will take a few minutes for the link to work.
