      Description

      How to replicate:
      create a function file with one of these two commands:
      give @s stone{display:{Name:"§ctest"}}

      results in either an instant game crash, or a game crash when you look at the item/mob.
      Most likely due to the new name formatting differences.

      This is especially problematic for worlds that have pre-existing data packs, functions, custom items, mobs, commands, etc.

      Extra note: this appears to work fine with "Lore"
