Hi,
A minor problem: I'm trying to place superscripted text in the text body -- things like '2^nd March'. I can't see anything like 2{\sup nd}, so my only known solution at the moment is math mode: $2^{nd}$. Despite this not being 'math', I don't really have an aversion to it. However, there's a problem with it: the superscripted text appears in italic Computer Modern. I'm using Gentium Book Basic as my body font, using XeTeX. The Gentium typeface is used perfectly everywhere, including the '2' in '2^nd', with the exception of the superscripted text.
So what solutions are to hand? Is there either (1) super/sub commands in text mode, or (2) a way of fixing this in math mode?
(Also, would this be a problem with ConTeXt or with XeTeX?)
