That seems wrong to me too.

I just experimented in TextEdit on OS X 10.9 — created some text in Avenir Next 
Medium, then italicized one word. It came out Avenir Next Italic (not Medium 
Italic), which is slightly wrong (too light) but not as wrong as what you got 
on iOS.

My best guess is that the metadata in the fonts themselves is wrong: maybe 
Medium Italic doesn’t have the same weight value as Medium.

 and, more importantly, is there a way for me to end up with an attributed 
 string that's using the italic version of the base font short of manually 
 walking each of the attribute runs and correcting the font?

You could try creating some CSS to define a custom font/style mapping, then 
insert that into the HTML…

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.

 and, more importantly, is there a way for me to end up with an attributed 
 string that's using the italic version of the base font short of manually

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.
