In Minecraft, there is a graphic bug:

This bug is related to the font in Minecraft, which does not support other languages (except English), and some characters.
From the photo at the bottom, you can see that in the world creation interface, when you write something in the name of the world, the font supports all languages and characters.
But when you write in a language other than English, in a book, in a chat, in a tablet, the font stops supporting them.

What you need to do:
Write a word in any language in the name of the world:
-What's going on:
All letters and symbols are supported.

You write in any language (except English), in a chat or other:
-What should happen:
The font supports all letters and symbols.

• What's going on:
  The font makes the letters smaller than usual.
