How do you validate when a missing address in Google blocks creation of the GBP?

[JS Girard]

I have a few strategies, but I'd like to hear people,s stories about extremes, particularly those that prevent even creating the GBP at all:

• The city in the address does not exist in Google
• The city name used by google for the address is incorrect
• The street name has changed since Google's last data update in, what, 2012??
• The street doesn't even exist in Google, much less have a name

This morning I had to deal with a case where the address exists in Google but you wouldn't be able to find it unless you knew that the city name in the address (and only in the address) has a mis-encoded accent character. I had never seen anything like that in Google!
