[BUG] Removing of backslashes on updates

After every updates on the javascript and css code with “Add CSS/Js by Duo Leaf” it removed the escape slashes from the content.

Before Update
content: "\f001";

After Update
content: "f001";

This bug is getting annoying as you have to double all the escape slashes before updating the settings every time. And if you forget it, the CSS will mess up your UI.
