Sorry, I need to come back to this issue.
I have migrated onto a new workstation (W7, 64bit, plenty of RAM) and are running the latest calibre 64-bit version.
Now I'd like ti regenerate some of the calatogs but am getting this old problem again.
Previously, the ticket got closed and I am not finding it on launchpad anymore. What do I do? Open a new ticket?
I have now a small libraray of just two books that produces this unicode error.
Thanxx for any help,
