See http://chris.improbable.org/experiments/browser/webfonts/universal-noto-sans/

http://chris.improbable.org/experiments/browser/webfonts/universal-noto-sans/all-in-one.html has multiple @font-face declarations which different font-family names and unicode-range declarations

http://chris.improbable.org/experiments/browser/webfonts/universal-noto-sans/single-name.html has multiple @font-face declarations with a single font-family name and different unicode-range declarations

In both cases, all of the referenced fonts are downloaded even when the unicode-range is not matched by text on the page
