It then says that the prefered way to indicate this encoding is with a Byte Order Mark. This is not advisable I feel due to: UTF-8 not requiring a BOM [3]; that it could cause problems with applications (apparently MSIE does or did have a problem) and programing languages (apparently inc. Java [4][5]); it causes otherwise valid ASCII to stop being ASCII. As such, I would swap the prefered method for indicating UTF inside the document and add a note about using the BOM. * By using <meta charset="UTF-8"/> (the HTML encoding declaration)(preferred). * By using the Byte Order Mark (BOM) character (could cause problems in some situations).
