☐ characters

Square character

I see ☐ character after uninstalling Custom ESC addon

This happens only on ItemsAdder version older than 3.3.0.

This is useful to uninstall Custom ESC addon

You have to delete this folder lang folder: data/resource_pack/assets/minecraft/lang

Then run /iazip command.

I see ☐ instead of my emojis/ranks

Make sure to run /iazip and reupload the resourcepack if needed.

You have one or more misconfigured images, these are the cause of that problem.

Example of misconfigured png:

This example pack has a PNG with height higher than the y_position.
