FontAwesome fails to load fonts locally and in electron app

I had a similar issue (perhaps this answer will help someone). I use Maven to build projects (Java + JS). Maven Filter Plugin corrupted binary font files. I had to add includes and excludes:

    <resources>
        <resource>
            <directory>${project.sources}</directory>
            <filtering>true</filtering>
            <excludes>
                <exclude>**/*.woff</exclude>
                <exclude>**/*.ttf</exclude>
            </excludes>
        </resource>
        <resource>
            <directory>${project.sources}</directory>
            <filtering>false</filtering>
            <includes>
                <include>**/*.woff</include>
                <include>**/*.ttf</include>
            </includes>
        </resource>
    </resources>
