Documentation fonts not currently included with the nightly binary tarballs

[alxgnon]

The nightly binaries provided on rust-lang.org do not include the fonts 'Fira Sans' and 'Heuristica' that should normally be located within the doc directory. This might be an issue with the build process or the rust buildbot, and could be related to the recent inclusion of these fonts to the local documentation. [https://github.com/mozilla/rust/commit/395d8857d60c66876d41484d6caea05c03882fad]

I'm going to try to identify the underlying problem. I will share my findings in a couple hours.

I tried building documentation with the current nightly version of rustdoc [https://github.com/mozilla/rust/commit/a692e9b1234ff6573b0cfbc39394d9222eb38f81] and sure enough, the fonts are not included even though they are referenced in the CSS. The font falls back to Helvetica Neue in my case.

Building the nightly's documentation into a Dash docset required some pretty nasty workarounds to make it truly offline: indirect/dash-rust@35fef55. It would be very nice if the WOFF files were included in the output of rustdoc and referenced in the @font-face declaration rather than the assets on rust-lang.org.

Sorry for the inconvenience, I believe that #13744 should have fixed this. Please try to rebuild with a recent master.

It is now uploaded on static.rust-lang.org through it will need configuration changes since it gives a 403 just now (see #13593 – repurposed).
