Unfortunately, the feedback link is next-of-kin to useless. Getting no response from them, and not knowing how many others have similar complaints is just pi**ing in the wind. If I am going to go to all the trouble to analyze a problem in detail and document the parameters, I am not going to just "throw it over the fence" and hope for the best.

To that end, I just got off the phone with Apple Support. They are aware of the problem and have a team working on it.
After discussing the issue at length, it seems that the best work-around is to use the iwork.com sharing gimmick. View the files from a browser and print (if needed) from the browser.
You cannot use the "download as PDF" from iwork.com, because it generates corrupted PDFs, just like iPad does.
It is also possible to be VERY selective about the fonts that are used when creating a document from scratch, but there is no easy way to know which fonts will work and which ones generate embedding errors.
In my experience, most of the new document templates will NOT work.

Anyway, the upshot is that there will be an update to the iPad Apps that will fix the problem. They do not know when that will be.
It is suggested that the more complaints that they get about the issue, the faster it will be fixed. It is POSSIBLE that the feedback link may do something in this regard.
If this issue is important to you, I would suggest taking the time to visit

and talk to a real, live, human being about the problem.
