OK, I've had a look at the data, but I don't see anything I would recognise as 'special characters in the column "MAC Addr"'. Please clarify. It's also not apparent where the following output data come from or to which of the first & last lines the "MAC Addr" in the table applies:

provision-ap copy-provisioning-params ap-name "«MAC_Addr»"
provision-ap installation default
provision-ap no external-antenna
provision-ap server-name aruba-master
provision-ap no syslocation
provision-ap no remote-ap
provision-ap no fqln
provision-ap reprovision ap-name "«MAC_Addr»"
