Two Unicode Characters Can Disrupt Functions in D2L for Non-IE Browsers
Two Unicode characters, the line separator and paragraph separator characters (U+2028 and U+2029), when used in the HTML editor, can disrupt a variety of functions on the page when viewed with browsers other than Internet Explorer. There are two documented examples of this. (1) If the characters appear on a Content page, the content is not visible to Firefox, Safari, Chrome, or other non-IE browsers. The navigation functions through the Table of Contents sidebar may also be disrupted. The content can be viewed if the window is undocked. (2) If used in Quiz questions, you can preview the questions with the unicode character and you can see the question text and choices when you are in the Add/Edit view, but when you attempt to edit the quiz you cannot; none of the buttons except Cancel work
If you encounter a situation where there is user-generated HTML content on a page that works with IE, but not with other browsers, please inform the Learning Technology Center. We will complete a Problem Reporting Form and ask our host Utility to contact the vendor to look for the offending characters.
