Thank you, Antonis, it works ! book.title = u'Verità' doesn't give any errors.
Just another step: suppose that the title with accented letters stays in a variable, say titolo, and I want to write book.title = titolo. It gives error. How can I do, when the assignment on the right is not a constant ?
