Don't understand 😭
Non-UTF-8 encoded characters are characters that are not encoded using the UTF-8 standard.
Basically, anything that isn't either English or symbols like '? @#&% glitch out
Anything (resources , files, …) in game that contain special character (like Ä, Æ, Ö, Ø,…) or special symbol (§, #, …) would make the game crash or won’t work properly.
If i’m wrong then someone would help me clarify it because i’m bad at English.
