<!--Notes:

The HTTP header attempts to set the character encoding to ISO 8859-15. The page starts with a UTF-8 signature.

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 <code>.test div.&#x00FD;&#x00E4;&#x00E8;</code>. This matches the sequence of bytes above when they are interpreted as UTF-8. If the class name matches the selector then the test will pass.

If the test is unsuccessful, the characters &#x00EF;&#x00BB;&#x00BF; should appear at the top of the page.  These represent the bytes that make up the UTF-8 signature when encountered in the ISO 8859-15 encoding.
