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. 27 28 --> 29 <script> 30 test(function() { 31 assert_equals(document.getElementById('box').offsetWidth, 100); 32 }, "A page with a UTF-8 BOM will be recognized as UTF-8 even if the meta charset attribute declares a different encoding."); 33 </script> 34 35 <div id='log'></div> 36 37 </body> 38 </html>
