I'm trying to integrate font awesome 5 into my project, using Sass.
The icons haven't been showing, but the files all load correctly, I eventually worked out that it's because it doesn't seem to escape the quotes correct.

This line

```
 @return unquote("\"#{ $fa-var }\"")

```

Should for example output

```
"\f00c"

```

But is instead outputting

```
\"\f00c\"

```

I've searched and this seems to be the correct way to escape quotes so I have no idea why it isn't working.
