What is the difference between varchar and nvarchar?

Question

Is it just that nvarchar supports multibyte characters? If that is the case, is there really any point, other than storage concerns, to using varchars

Answer 1

Follow Difference Between Sql Server VARCHAR and NVARCHAR Data Type. Here you could see in a very descriptive way.

In generalnvarchar stores data as Unicode, so, if you're going to store multilingual data (more than one language) in a data column you need the N variant.
