SASS compile fontawesome preserve notation

Question

When I compile fontawesome.scss to a css file with sass 3.4.1

$fa-var-music: "\f001"; 
.#{$fa-css-prefix}-music:before { content: $fa-var-music; }

it is compiled to

.fa-music:before {
  content: "";
}

As I'm mainly using Win1252 encoding in my project I'm wondering what's the way to preserve "\f001" in the css file. Why does SASS rewrite?

Answer 1

Extract from Sass 3.4.0 changelog: Sass now follows the CSS Syntax Level 3 specification for determining a stylesheet’s encoding. In addition, it now only emits UTF-8 CSS rather than trying to match the source encoding.

Now no way for use old method

Issue on SASS repo

For me, rollback to SASS 3.3.14 fix this
