How to insert a .css file via sass so that it outputs the content and not @import?

Question

css

Good afternoon. I said the Roboto font, there is a roboto.css file that adds it. I want to add it via sass @import 'fonts/roboto/roboto.css', but in the output css the file appears @import url(fonts/roboto/roboto.css);and not the content. I've tried @import 'CSS:fonts/roboto/roboto.css'the underscore as well. Is it possible? Thank you in advance for your help.
