This erroneous translation of content in the Editor in IE9 and IE10 is due to a browser bug in Internet Explorer that does not handle the removal of spaces in rich text content. This issue has been raised to the Internet Explorer development team on Microsoft Connect: https://connect.microsoft.com/IE/feedback/details/797879/deleting-or-replacing-text-in-an-iframe-in-designmode-adds-rogue-nbsp-entities
Still no information on when this issue is going to be fixed. We have had a ticket open since february and still no information from support except a small amount off our renewal (yay, im sure my customer will be happy we are saving money) and a constant promise that the priority has raised. I don't think the priority can get any higher without becoming a matter of national security. Any chance telerik want to fix this major flaw on their editor? As stated many times pressing delete is a major part of editing!
Any idea how soon this will be fixed?
