The language stuff should be automatically generated from the fonts
themselves. I suggest basing that on what Fedora has done for
automatic font installation with PackageKit:

https://fedoraproject.org/wiki/Features/AutoFontsAndMimeInstaller

The technical details are that they run fc-query --format '%{=pkgkit}'
/tmp/newathu.ttf, which gives output like this:

$ fc-query --format '%{=pkgkit}' /tmp/newathu.ttf

fc-query will hopefully become available to Debian when fontconfig
2.7.0 is released. The output above is based on RPM's PROVIDES thing.
For Debian we could either invent another control field or use
"Provides: font-lang-<code>" in binary packages and Provides:
${font:Provides} in source packages and create a dh_font_provides or
similar.

fc-query also has human-readable output not dissimilar to the fc-match
-v output:
