EM12c: Reports not running due to special character in password

I have told you about my adventures with passwords before, but today is a new type of issue!  Instead of the EBS application, the MOS document "EM 12c: Enterprise Manager 12c Cloud Control BIP Reports do not Execute if the User Login Password has a Special Character (like $)" found via note ID 1951651.1 is about encountering error messages when trying to view BI Publisher reports if the account has a special character in the password for the account.  Is that because special characters are not allowed?  Nope, they are perfectly valid characters but do not interact well with BI Publisher report output files!!
