[A Lurker]

I purchased an ebook from Kobo (epub format), imported it into Calibre (using a plugin to remove the DRM), then sideloaded it to my Kindle using my Send To Kindle email address.

The book displayed oddly on my Kindle. All of the apostrophes and quotation marks were replaced by a series of symbols: ’ (a-circumflex, Euro, superscript trademark). For example, the sentence: "I'm not sure why you don't run away." displayed as: ’I’m not sure why you don’t run away.’

I took the same file I'd emailed my Kindle and opened it with Calibre's native viewer. The punctuation displayed correctly there. That suggested the original file is fine; the problem occurs when Amazon converts this epub to awz3.

As a test, I created a mobi version with Calibre and sent it to my Kindle using the desktop Send To Kindle app. (Send To Kindle email no longer allows uploads of mobi files, but the desktop app does.) This time the book displayed properly, confirming the error was an artefact of Amazon's converting the epub.

Bottom line, I found a solution, so I'm not posting here to ask for help. I just want to share my experience in case anyone else runs into this issue. If Amazon screws up your epub, trying sending a mobi version with the desktop app (as long as that remains as possiblity... I believe the desktop app will also eventually drop mobi support).

Out of curiosity, has anyone else come across this? I've had a book's formatting display differently on a Kindle compared to its appearance in Calibre, but this is the first time I've had actual text get screwed up.
