How can I import ISO-8859 files into IntelliJ for a Maven project?

Long story short I'm trying to switch over from Eclipse, but IntelliJ really doesn't seem to like the fact that my files have the following character:

§

I don't know much about file encoding, but I managed to dig thru enough to find out Eclipse saves files in ISO-8859. So I changed the following in my pom:

<project.build.sourceEncoding>ISO-8859</project.build.sourceEncoding>

and got this error:

Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.6:resources (default-resources) on project PlayerTracking: ISO-8859

Can somebody please help? I'm at a loss, I really need to convert this project to IntelliJ (and subsequently Maven) and I can't find anything regarding this
