Fast and efficient support for serving large fonts which cover many languages

Any chance of using the hint to not download unused fonts? - it would be a huge win for Google Fonts users if we could leverage unicode-range on Edge :)

Note that unicode-range is supported in IE, but only with uppercase U in the <urange> value(s). This was the way it was specified in an earlier version of the spec. https://twitter.com/sgalineau/status/533040806290927616
IE also doesn’t use this hint to not download unused fonts.
