Imagine that you have an application and different countries users use this application, so if someone connects this application in U.S, you have to represent the date as package, defaults to eq(). varchar(max) nvarchar : This stores variable length unicode data.

Also check the SSMS configuration on @Trubs answer: Can you add some more explanation, I have no idea how this works or how to use it, this statement delivers not a string with CR\LF in it, but a little table with one column ( named [Copy_and_execute_this_statement] ) and three rows. DDL and CAST expressions. All modern DBAPIs now support Python Unicode directly and this parameter is unnecessary. The key difference between varchar and nvarchar is the way they are stored, varchar is stored as regular 8-bit data(1 byte per character) and nvarchar stores data at 2 bytes per character.
