Summarized test results:
CSS3 Syntax, Input byte stream

Intended audience: users, XHTML/HTML coders (using editors or scripting), script developers (PHP, JSP, etc.), CSS coders, Web project managers, and anyone who wants to know how character encoding detection works in current browsers for CSS style sheets.

These tests check whether user agents recognise character encoding declarations as described by the CSS Syntax Module Level 3. The test pages have HTML5 syntax and are served as text/html.
