A hyphen in Operator ID
Hello!
I have the following question: what's wrong with a hyphen in Operator ID? Why we can't create an operator since PRPC 7 with a hyphen?
We have a system upgraded from PRPC 6.2 sp2 to PRPC 7.1.9, and we had a lot of old users with a hyphen in their IDs. Will the system work correct for these operators?
I have found these support articles (https://community.pega.com/support/support-articles/special-characters-operator-id, https://community.pega.com/support/support-articles/issue-creating-operator-id-hyphen), but the didn't helped me to understand the problem.
