There is no policy for that as far as I know, but all information on a wiki should be kept as accurate as possible to the source, and that includes accent marks. So to answer your question: If the source uses them (e.g. TV Show captions/descrip, creator comments, translations), then keep the consistency and use accent marks!

If there's multiple official spellings of the same name though, go with the one that's most commonly used.
