One way might be to just run woff2_compress in a test and see if the result is the same as what's in git. A test like this would probably be added to ReleaseCheckListTest. Would need to add woff2 to travis.

woff2 is not available as a package on travis, but it seems it can be built from source (and then added to a travis cache directory), see:
