I speak Spanish and I configure in Spanish I have problems with signs, when putting one of these: "¿ ¡ ñ q" For example here an image I need help please
UTF-8 is the Java symbol for color codes and special characters. They often start with "\u00A7". This link will be of use.
They are both symbols, but UTF for Java. However i don't think that he created the plugin, he saw "i configure in Spanish" so i think it's a public plugin. If the plugin isn't yours you can't use symbols, if the plugin is yours you can save the class with UTF-8
How sad, although I have seen servers that are in Spanish and did not have this kind of problems, anyway thank you for answering me
