Glyphs compiled incorrectly

[joneff]

This bug has already been fixed with sass/libsass#1231

But in essence, while the following compiles correctly:

.icon:before {
    content: "\e000";
}

If you assign \e000 to a variable and then use it you get unexpected output:

$char: "\e000";

.icon:before {
    content: $char;
}

@charset "UTF-8";
.icon:before {
  content: ""; }
