What is the best method for disabling or removing fonts that are unneeded, such as greek, latin, vietnamese, etc? Loading these fonts can take some time over a cellular modem and makes the initial connection to the application appear slow.

I found 2 packages, OpenSans and Roboto, under /web/resources/fonts but I am unsure the best way to disable them. I am a little hesitant to remove them all together as I don't know their impact on the rest of the application.

Any suggestions?

Thanks
Ian
