Issue description

I'm having trouble changing the name of an item as it appears in a book im making for my modpack, the website page 'ItemStack String Format' suggests:
namespace:path{nbt} (e.g. "minecraft:diamond_pickaxe{display:{Lore:['A really cool pickaxe']}"
But even when copying this exact example, the book has a loading error.
I've implemented plenty of enchantments and other nbt values, but this one is giving me trouble, any ideas?
