No encoding declaration
Test passes if you see a green box.
Assertion: A page with no encoding information in HTTP, BOM, XML declaration or meta element will be treated as UTF-8.
The test on this page contains a div with a class name that contains the following sequence of bytes: 0xC3 0xBD 0xC3 0xA4 0xC3 0xA8. These represent different sequences of characters in ISO 8859-15, ISO 8859-1 and UTF-8. The external, UTF-8-encoded stylesheet contains a selector
.test div.ýäè. This matches the sequence of bytes above when they are interpreted as UTF-8. If the class name matches the selector then the box will turn green.
