☐ 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.
Read more here: resourcepack hosting​
Make sure y_position property is not greater than the image height in pixels or imagine height * scale_ratio.
Minecraft doesn't support this, it won't work.

1.19 clients show ☐ instead of some font images

This is caused by this Minecraft bug I cannot fix:​

How to fix?

It's very easy: you just have to open your CLIENT log (not server log) and find the error about the font shows which what caused other font images to stop loading: reading client log​
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.
Unable to load font 'minecraft:default' in fonts.json in resourcepack: '260e803a4ce18a1662a5ff9c59f9d758ab1026bb' Ascent 30 higher than height 9
