Unicode strings
Unicode strings have a format similar to character strings but are preceded by an N identifier (N stands for National Language in the SQL-92 standard). The N prefix must be uppercase. For example, 'Michl' is a character constant while N'Michl' is a Unicode constant. Unicode constants are interpreted as Unicode data, and are not evaluated using a code page. Unicode constants do have a collation, which primarily controls comparisons and case sensitivity. Unicode constants are assigned the default collation of the current database, unless the COLLATE clause is used to specify a collation. Unicode data is stored using two bytes per character, as opposed to one byte per character for character data. For more information, see Using Unicode Data.
Unicode string constants support enhanced collations.
