Hm, it’s not a support, it’s a requirement. We should require node 4+ for grunt-webfont too.

Not anymore with the last ttf2woff2 update, in fact it is now compatible with at least Node 0.12. In all cases though, when the build fails the emscriten fallback still works.

@sapegin can we bump grunt-webfont version and publish to npm also please?

[nfroidure]

We're about to make it build on windows too nfroidure/ttf2woff2#13 (comment)

Just wait a bit, we'll warn you asap.

[sapegin]

@fernandopasik I’d wait for Windows support too.

Oh ok! Thanks @sapegin @nfroidure !

@nfroidure Hey is it ready? ;-)

Not yet, i'm changing the emscripten build to use bindings and maybe avoid the AVG antivirus warning.
