I think it would be the right thing to do, but unfortunately it is 
possible to inject (CSS-unescaped) surrogates into CSS though JavaScript:


data:text/html,<style>body:before{}</style><script>document.styleSheets[0].cssRules[0].style.content="'-\ud834\udd1e-'"</script>


data:text/html,<style>body:before{}</style><script>document.styleSheets[0].cssRules[0].style.content="'-\ud834-\udd1e-'"</script>
