Different GNU Unicode Versions

[Nydid]

Problem Description

In 1.21, the GNU Unicode was updated and some symbols are not available for older servers. Some symbols have also changed width. This makes writing in books and quills a lot harder because the visuals are not the same:

Book on 1.21 Client on 1.18 Server

---

Same book on 1.18.2 Client on 1.18 Server

---

Other example:

Solution Description

Would it be possible to revert to displaying the corresponding GNU Unicode versions for each version?

Alternatives

Going back to a 1.18 version to write all the book and quill contents, without any of the helpful 1.21 mods.

Here is the RAW NBT Data file:
Book NBT Data.txt

Here it is after an attempt at cleaning it:
Book NBT Data Cleaned.txt

Here is a command to run in a command block to only get the block characters on a 1.21 client:
