[font="Verdana"]Hi Sumit,
You are right to insert a character other than english you need to declare the column as nvarchar and while inserting the data also use N infront of the data to inform SQL Server as unique character. An example is shown below, here im inserting russian character
CREATE TABLE #tmp(description NVARCHAR(15))
INSERT #tmp VALUES (N'?????')
SELECT * FROM #tmp
description
---------------
?????
(1 row(s) affected)
I hope this would hel you![/font]
