I found that if I use any alternate characters from your character map that Auctiva has a problem listing that item especially if you use it in the title. Example is using * È * instead of * e * and using * ¢ * instead cents.
Any idea when Auctiva will have this fixed. It is nice to use those just in case you have an international book that uses the * È * instead of the American *e*
So if you have this problem like I did just use the American version and then edit your auction after it is listed.
Hope this helps someone
