Symbols not showing on PaperSpigot

[Cadey]

Hey!
So recently I switched over to PaperSpigot and upon switching I noticed all of my configurations with block symbols turned into an "a" with a line. Although I'm not sure what caused this I'm assuming it was cause by the PaperSpigot because all these messages were fine on normal spigot. Does anyone know why this is happening or how to prevent it?

Example:

Turns Into

I believe all Unicode symbols have "\" codes assigned to them in Minecraft, I don't have a full list. But the few I know are the following:

» = \xbb
« = \xab

Should be something like the following for every other symbol.

Alright ill try it out thanks.

Yeah IDEs don't like to compile with special unicode characters, so your going to have to use an actual char and like 1 person said, it does start with a \. Here's some examples:

"\u2022" = •
"\u2764" = ❤
"\u221E" = ∞

These are all chars, so feel free to use them with the right data type. I like to use http://www.fileformat.info/ when searching for unicode characters, so just do a google search like this: "Heart Unicode" and file format will tell you everything you need to know. Where it as the "C/C++/Java source code" tab, that's the one you want to use.
