OK, fair enough... If that is the normal behavior, I'll make a note in the associated documentation.

Thanks anyway.

To be complete this is what I have done in the very first line of identify():

        debug=self.dbg_lvl & 1
        if debug:
            log.info("title             : ", title)
            log.info("identifiers       : ", identifiers)
            log.info("authors           : ", authors)

        nknwn = ['Inconnu(e)', 'Unknown']
        for i in range(len(nknwn)):
            if authors and nknwn[i] in authors[0]: 
                authors = None
                break
            
        if debug:
            log.info("authors corrected : ", authors)

If switching between language, the nknwn list should be completed. I may add French Canadian, Italian and Roman too...
