XML declaration vs meta charset
Test passes if you see a green box.
Assertion: The XML declaration has a higher precedence than an encoding declaration in a meta charset attribute.
The XML declaration attempts to set the character encoding to ISO 8859-15. The meta charset attribute tries to set it to ISO 8859-1.
The test 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.ÃœÃ€Ãš. This matches the sequence of bytes above when they are interpreted as ISO 8859-15. If the class name matches the selector (ie. the XML declaration overrides the meta element) then the box will turn green.
