Written Books do not support JSON when naming them or its author

Written Books do not support JSON when naming them or its author; in other words, using the "title" or "author" tag on Written Books in order to do so. Using the "display" tag on other items supports JSON however.

What I expected to happen was...:
When I type in a specific command to name a Written Book, it should have Hello! as its name.

What actually happened was...:
It just became a raw string instead of a customized name; refer to pictures below for more information.

Steps to Reproduce:
1. Type in the specified command below.
2. Notice that it is just a raw string instead of a customized name. How can I customize names of Written Books now without having to use this symbol (§)?
