Little White House. Georgia State Parks and Historic Sites. At Warm Springs, Franklin D. Roosevelt, 32nd president of the United States found the strength to resume his political career and a positive outlet for his own personal struggle with polio through creation of the Warm Springs Foundation.
On the other hand, VARCHAR is a variable length Data Type. For example, if you declare a variable/column of VARCHAR (10) data type, it will take the number of bytes equal to the number of characters stored in this column.
If your column will store a fixed-length Unicode characters like French, Arabic and so on characters then go for NCHAR. If the data stored in a column is Unicode and can vary in length, then go for NVARCHAR. Querying to NCHAR or NVARCHAR is a bit slower then CHAR or VARCHAR. So don't go for NCHAR or NVARCHAR to store non-Unicode characters even though this data type supports that.
