Continuity mistake: Deckard shoots Zhora twice. Both times she is shot, you can see the wound explode out of her right shoulder. But moments later when she is on the ground dead, she is face down and you can see a bullet wound on both right and left shoulders. (00:58:50)
Answer: The two most notable hints are as follows. The first (which is only in the Director's Cut) is that after Deckard dreams of a unicorn, Graf makes an origami unicorn and leaves it at Deckard's apartment. Some people interpret this as suggesting that they're aware of the memories that have been given to Deckard to prevent him realising his true nature. The second hint is that replicant eyes glow in certain lights - at one point in the film, Deckard's eyes can be seen glowing in the same fashion. Ridley Scott has stated on several occasions that, as far as he's concerned, Deckard is a replicant, but he does concede that they deliberately left it as somewhat ambiguous - the viewer should decide for themselves.
