There may be several possible reasons for such behaviour. Since you have not specified the database you are working with, we explain them using Oracle database as an example.

1. Database encoding must support Arabic characters. If database encoding does not support Arabic characters, NVARCHAR/NCLOB fields must be used to store textual data instead of VARCHAR/CLOB.
2. The 'Unicode=true;' connection string parameter must be added to the connection string for exchanging data in Unicode format. This parameter is available only for providers that support it.
