I just specifically set up an <em> run to use Avenir Next Medium Italic and I can't see any difference in font weight, so if it's something like that then the algorithm that makes that determination is pickier about it than I.

I'm doing this same sort of thing in several locations within the app which would mean providing CSS for each as a workaround. Not the most elegant solution but for now I have ended up post-processing the attributed string, replacing the font in italicized runs with an italicized version of the base font. If someone else can provide further enlightenment into something I've done wrong and how to fix it then I can rip out this bit but for now this will do.
Thanks, Jens.
