When the name of the person injured is substantial and not merely descriptive, such as when the injury is to the person, as in murder, rape, or battery, the indictment shall state the true name of the victim or the name, appellation, or nickname by which he is known. If the name, appellation, or nickname of the victim is not known, it is sufficient to so state and to describe him as far as possible. In stating any name of a victim it is sufficient to state a surname, a surname and one or more given names, or a surname and one or more abbreviations or initials of a given name or names.
