For the field to be able to store unicode characters, you have to use the type nvarchar (or other similar like ntext, nchar).

To insert the unicode characters in the database you have to send the text as unicode by using a parameter type like nvarchar / SqlDbType.NVarChar.

(For completeness: if you are creating SQL dynamically (against common advice), you put an N before a string literal to make it unicode. For example: insert into table (name) values (N'Pavan').)
