We are developing e-learning courses in Lectora 11x and are currently facing characters that show up as squares when we publish this in v11.3. This junk character issue is only visible on IE 8, but it shows up fine on IE 9 and above. The possible solution is that we can upload windows 7 default fonts on the IE 8 system and the issue is resolved. But what if someone cannot upload the fonts? What is the solution then?
