If I provide the text for the title of a book, I don't expect it to be corrupted into non english charaters, that is what is happening with video generation - how do I specify the existing cover of a book to appear inn a video?

I have attempted to create a video with a specific book cover to create a ‘video trailer,’ however, the book cover image as I suggest never appears and some wild non-english characters seems to fill image - rather than the real book cover. How do I change this?
