SSMS Scripting Options

Scripting a function using SSMS 18.0 Preview 6 produces the following script.

Scripting the same function using SSMS 2016 produces this script

Question - What scripting option(s) do I need to change in SSMS 18 so it does not add the N' prefix and double-quote ''string literals'' in the output script generated using Right Click->Script Function as->CREATE TO or Right Click->Script Function as->ALTER TO

This option works but I do not wish to drop the object Right Click->Script Function as->DROP and CREATE TO

PS: I can't remember if I had changed something under scripting options in SSMS 2016 to make this happen or if it was the default setting. Thanks!

You could change this behavior under:

SSMS->Tools->Options->SQL Server Object Explorer->Scripting->Object scripting options

For SSMS 16, the property Include IF NOT EXISTS clause should be set to False

For SSMS 18, the property Check for object existence should be set to False
