Special characters not working

Fixing the config.yml file encoding

To fix the issue, you'll have to save your file with the file encoding UTF-8, here's how to do it on multiple different editors.

Encoding > Encode in UTF-8
Encoding > Convert to UTF-8
File > Save with Encoding > UTF-8
Edit > Select Encoding > UTF-8

Editing your launch script

This only works if you have full control of your host, and the launch script.

If changing the file encoding of the config.yml file didn't work, then editing your launch script might work.

You'll have to add the parameter -Dfile.encoding=UTF-8 to your launch script, here's an example:

java -Dfile.encoding=UTF-8 -jar spigot.jar
java -Xms=256M -Xms=1024M -Dfile.encoding=UTF-8 -jar spigot.jar
