Make sure your EPUBs are using utf-8 in order to avoid the funky characters. (Convert to EPUB -> Look & feel -> Text -> Input character coding: -> utf-8)
Otherwise, do what I do and convert to MOBI and then back to EPUB. Amazon does a garbage job of converting from EPUB format, so doing the EPUB->MOBI->EPUB removes all the fancy formatting that they can't handle. It's annoying but it works, as you've seen.
