<!--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.ýäè</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  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.
