Should we use characters other than ASCII in CSS file

[foxfox]

such as the name of a particular font in foriegn language?

or even CSS comments?

No reason not to that I can think of (in fact CSS2.1 explicitly requires UTF-8 support [w3.org]). You’ll obviously need to set the server’s HTTP encoding type up correct, and it probably wouldn’t hurt to put an

@charset

rule at the top of your stylesheet:

@charset "UTF-8";
