All strings must be XML compatible?

talzag · 04-10-2013, 09:31 AM

I just bought a kindle book on Amazon. I try to view it on Calibre but I get the below message. I can't view it nor convert it.

This is the first time something like that happens. Usually I can view books no problems.

Any help would be appreciated!

Thank you.

Your version of calibre is ancient, update.

This exception still can occur with recent calibre 5.11, e.g. with PDFs containing strange characters in their metadata for title, author and so on.
