Obviously, feel free to do your own conversions if you don't like mine.
In that case, I think the solution might be very very very simple if the problem is what I think it might be. Go to the Make Sony Reader dialog and then the options tab. Under misc, what are dashes set for? In order to have emdashes, it should be set for "as it is" and then if your text has emdashes, they will come out as emdashes. I'm surprised I didn't think of this earlier.
