I have found that NSSuperscriptAttributeName,

subscript, positive obliqueness is a leftward tilt, etc. In normal
controls the attributes render as expected.
Make sure that you are drawing in a flipped context.
I was ensuring that I am _not_ drawing in a flipped context... (!)
now, as you suggest I tried flipping the custom view (override
isFlipped) that the attributed string is drawn in, and note that it
works correctly!
So an improved workaround is to tweak the positioning logic (to
account for the flipped context) instead of tweaking (hacking) the
actual attributes.
I'm still not clear on why this should be the case. Thanks for the
vastly better workaround though..
thanks
Rua HM.
