I have a R77.30 that I'd like to upgrade to R80. When I run the pre_upgrade_verification tool it comes back with the error "Objects with non-Unicode characters" in the tables network_objects and sem_network_objects. I went through the object names of every item in both tables but couldn't find a non-unicode character. I don't want to use non-unicode characters anyway, so I'd change them to be compatible if I knew which objects we're talking about. How can I find out which object exactly causes this issue?
