The problem here is that Reporting is trying to use a system font when loading Kibana. Most likely you don't have any fonts installed on the server, so you get the box characters instead of actual text.
The solution is to install a font on the system. google-roboto-mono-fonts works, but doesn't look very nice. Adding Open Sans (open-sans-fonts) would likely produce better results.
