[DC COMICS] Does Batman knows how Jack Napier became the Joker? If so, what are his thoughts abut it?

Edit: about it*
gpt
Jack Napier is only the Joker in the Tim Burton movie. Fun fact: the name itself isn’t a hidden message or reference to the Joker. It’s just an homage to Alan Napier, who played Alfred in the 1960s Batman show. 

In the comics, no one knows Joker’s real name. He’s used false identities like Joseph Kerr, Jack White, and Eric Border before, but no one knows who he really is. Actual telepaths have read his mind and not found that information. Even the *Joker* doesn’t remember who he is anymore. 

Also, there may or may not actually be three Jokers, one of whom is a centuries-old immortal demon. That idea was introduced in the New 52, but the writers just kind of forgot about it.
