Hawking Radiation is theoretically not at all related to the contents of the black hole; it should be random.

However... that means that when a black hole evaporates completely, all information that entered it is destroyed. This is a huge open problem in quantum physics known as the Black Hole Information Paradox.

Interestingly, one recently discovered possible solution is that information is able to exit the black hole via wormholes that could mathematically exist, but don't... https://www.youtube.com/watch?v=epSev7ovVew

But really, we just don't know yet for sure. It's certainly possible that Hawking's original description of Hawking Radiation is incomplete or subtly wrong.
