Why does the preprocessor break Cyrillic?

Question

css

How to solve the problem?
I write in sass code

p.speed:after{
  content: " Мбіт/c";
}
p.price:after{
  content: " грн/міс";
}

and in css it turns out

p.speed:after {
      content: " ╨Ь╨▒╤Ц╤В/c";
}
p.price:after {
      content: " ╨│╤А╨╜/╨╝╤Ц╤Б";
}

Is it possible to set it all up somehow?
And explain what xxxx.css.map
ps does in sass is there a difference when to insert "import" at the beginning or at the end of the file?
