Meaning of pound (#) in a regular expression

Question

I have a regular expression with a pound # modifier.

What does \\# mean in a regular expression? What does the # mean in a regul

Answer 1

I just had this same issue. It turned out that the prior programmer "missed" when changing all the "old code" from # to | and it was a simple mistake. I found this by checking all other code in the app and found NO other # symbols, but many similar areas of code with | included. And the | was right next to the # in this code. So someone was swapping out old regex for new regex and "missed".
