When I run command

calibredb add -r ../Books/native/ --with-library .

I get an error

TypeError: Not a unicode string

First of all, "Ian Flemming" looks very unicode-y to me. Second of all, I would like to have information about particular file which causes an error. Third of all, I would like to solve this issue

If there is a way to turn on some debug/verbose logging for calibredb add —*that would be cool.

I do this all on my server, so I can't use desktop calibreversion. That's why I'm trying to setup calibre-web + calibredb

Any ideas how can I fix it?
