I'm configuring Ubuntu 18.04 LTS PCs for a school in Italy, and I've seen that more than 200 fonts got installed as dependencies of `ubuntu-desktop` package. 

We don't need most of them, we don't expect tipycal users to write or read documents in Bengali or Thai, for example. Actually, so many fonts make font choices more difficult for our users (for example in LibreOffice), because it makes difficult for them to find useful fonts. 

Is there a way to disable those non-Latin fonts system wide, so they don't appear in applications?

I know I could manually remove them (for example purging `fonts-tlwg-*` packages), but I want to keep them installed, so single users can enable them later on if needed, without affecting other users of the same system.
