When choosing to display a foreign audio track on some videos, the text does not render correctly. instead of a musical note I see white boxes for instance. This issue does not occur for the same content on Safari for Mac or Safari for iPad. The issue does present itself for a native mobile app (AVPlayer) on the same iPad, Safari for iPhone and the native mobile app on iPhone. Below is an image of the issue, the left is what I see on a problematic device and the right is what I would expect. Are there any known issues or workaround for this?
