My webpage data appear as ?????

[Guest_imported]

I host my website in an USA company and i use coldfusion to use database>
the database that i used is SQL server2000 and Access and the two databases are in USA.
My website is in arabic language.. and when i store data on SQL server database ,the data appear on page as ?????? not in arabic.

Is the problem related to collations ?!
My database collation is SQL_Latin1_General_CP1_CI_AS that means english location.
I tried to transfer data to Access database but the problem not solved and data still appear as ??????????

I guess that the solution of my problem is to change the Collation of database from SQL_Latin1_General_CP1_CI_AS
To SQL_Latin1_General_CP1256_CI_AS ... Is this True?

Is there a solution to change collation after i created the database?

Is Access Database has collations as SQL Server?

HELP me Please to silve the problem>..
