VS Error: Octal escape sequences are only supported in ECMAScript 3 compatibility mode

css, less, twitter-bootstrap, visual-studio-2010

Solution

Just wanted to say that I had this error too, and the problem for me ended up being with Chirpy. I tried to make a merged css file with it, but i was using .min files and i didn't use the chripy Minify="false" parameter in my File node. Added that parameter and that fixed it right up

Problem

I have twitter bootstrap setup to build in a new project, but am getting the following error from VS2010. Fatal error, cannot continue: Octal escape sequences are only supported in ECMAScript 3 compatibility mode. Which seems to be related to the following CSS/Less entry in bootstrap (type.less)... ``` blockquote small:before { content: '\2014 \00A0'; } ``` Can anyone help?
