Disappearance of colors in item names

Describe the bug When players change their world and therefore their inventory

Renamed items end up losing their colors and end up with lots of "?"

I use the name of the colored items as much to make items unique because we cannot put color in the vanilla game in an anvil for example and this problem literally destroys a lot of aspect of the server.

The silk spawners for players with a rank no longer work after a few minutes / hours if the player changes world several times
Items won in events no longer work after a few minutes / hours if the player changes world several times

All this also includes the content of the enderchest

Plugin version PWI last version on SpigotMC (2.3.2)
