Is it come from LESS ? I don't know.
In one of my rails project, it will throw an error in my colleague's mac.
I just change it to \9, like other SCSS file does.
And everything looks fine.
fix wrong typo
The original LESS code has the e("\9")
After a research on that.
I find e() is the escaping function in LESS.
and \9 is a IE hack.
So I'm sure the e("\9") here is wrong.
The correct one is \9
It hurts with compass gem 0.12.0 and above.
But it is fine with compass gem 0.12.rc.1 or without compass gem.
It should be correct without e() function.
Thanks for PR. But bootstrap-rails gem pulls sass from http://github.com/yury/bootstrap. Next time, please send PR against that repo.
Applied manually. Released v18.104.22.168
