Sass + Autoprefixer + Sourcemaps

[MethodGrab]

If you have unicode symbols anywhere in your Sass (eg: pseudo element content property), it will cause the sourcemap to not appear in Chrome when using gulp-sourcemaps with gulp-sass + gulp-autoprefixer.

It seems to be just the symbols, if you replace them with hex representations then sourcemaps work.
It also appears to be autoprefixer related as compiling with symbols but without autoprefixer does show the sourcemap correctly.

I made a reduced test case which demonstrates the issue and has more detail here MethodGrab/gulp-sourcemaps-test-case.

Possibly related: #8

Please read the readme. Should be opened at the autoprefixer issue tracker.
