I saw a server description using UTF8 and I would like to do the same. I tried copy/pasting the symbols in the "+server.description" but it did not work. How do I do that? Do I need to use "\u#CODE" or something like that?

You need to change your bash file's CHCP

Hmm, ok. So I need to add “+chcp 65001”?
Thank you for the help!
