Script: AD-GROUP-Monitor_MemberShip.ps1

Reported by Michal Burda: when csv was imported/exported there was a difference in local characters so script reported at first run that all users where removed and all the same time were added, I had added parametrer -Encoding in lines 606 and 616 and that fixed issue - for English/US users should be fine - problem occurs with national characters in usernames
