Minecraft plugin special characters?

I have a question about a plugin. I use a chat plugin that shows special characters in a very strange way. Hence my question, how can I insert special characters without a placeholder. I heard "\ test123" or something like that with some combination, which you can then insert (no placeholder) becomes an Ü. "UTF-8 code" or something like that.

Can someone send me the codes for these 2 characters?

Does not work, have the correct rank, the prefix is only written out in the chat, so no special characters are displayed.

Choose a special character you want and edit the config or whatever with notepad ++ and insert the character with it and set the encoding to UTF-8

Where did you put it in?
