Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.

But when I link the database using Access Database, all the records with
Chinese character will appears as "#Deleted" in the table in Access. What is
wrong? Any idea?
Thanks again.

As David has mentioned you should use NVARCHAR(n)/NACHAR(n) datatype to
transfer unicode characters
CREATE TABLE #Test (Col NCHAR(12))
DECLARE @.nstring nchar(12)
SET @.nstring = N'?kergatan 24'
INSERT INTO #Test VALUES (@.nstring )
