Comment 3 for bug 1576303

I also needed to add these variables to package a Racket/Scheme game that I made several years ago.

I also needed to bundle some fonts with the snap, namely fonts-dejavu. Without them, instead of letters, only rectangles were displayed. In case of Java, it didn't even start.

Snapcraft should handle these variables.
I also think that snapd should grant access to the fonts and fontconfig directories/files of the system and user. That would be really useful for things like LibreOffice.
