Some, not all, of the epub books I add to Calibre, with DRM stripped via plugin, have from one to three characters where the punctuation and accented characters should be. i.e. “ in place of “, ç in place of ç, and é in place of é. The text reads fine in Adobe, while still infected with DRM, but is not right after stripping DRM.

Any ideas on why this happens? Or, better still, how to prevent it from happening?

I can do a search and replace in Sigil to correct the problem. It's not too bad when only the quotes, apostrophies, ellipses, and dashes, are affected, but it's a major pain when a book has a lot of non-english words with accent marks.
