The nvarchar data type provides support for Unicode characters. This is
needed if you are building an international system that must store different
languages. However, if you have no need to store Unicode characters then you
are better using varchar. The nvarchar data type occupies twice the space of
varchar as it uses 2 bytes to encode each character.
