Documents with non ascii characters are not properly handled
When processing the file "AXES &é'(-è_çà)=°+#{[`^@]}$£¤µù%¨!§;.,-Promo.mp4", an error occurs in Limas even if the special characters have already been stripped. The video has been stripped to is vAXES_é_è_çà_µù_Promo. However it seems that non ascii character are causing troubles. The should be removed from the input file name too.
