Why?

What RDBMS are you using? What version of Delphi are you talking about? How do you access your server? What makes you think the field doesn't support Unicode?

I used dbExpress to connect to SQL Server.Column type is ntext and field editor adds a TMemoField for it.I set the value of the field using a TDBMemo control (with Arabic charset) and After apply updates and then refresh (using CDS) , the value of the field is incorrect and unreadable.

What collation and character set do you have you on your SQL Server tables in question? Is that set so that it would support Arabic characters?

You got in few problems: 1) Delphi TDataSet infrastructure does not support Unicode BLOB fields directly. IOW, there is not TWideMemoField or ftWideMemo data type. But TMemoField may be used. Just set Transliterate = False. Or you can create TBlobField by hands. 2) Borland MSSQL dbExpress driver does not support Unicode. So, rather you should convert your field into binary BLOB value. For example: select cast(cast(Description as nvarchar) as varbinary) from Categories As option, go with ADOExpress or Open ODBC dbExpress driver. 3) TDBMemo supports ANSI character set only. You should use 3d party Unicode controls, for example: http://tnt.ccci.org/delphi_unicode_controls Regards, Dmitry -- Dmitry Arefiev, gs-soft Company, community.gs-soft.com Personal - www.da-soft.com SAPx - Delphi to SAP R/3 direct access Saphir - SAP R/3 metadata on your fingertips MetaBase - ERWIN model in Delphi applications NCOCI8 - Freeware Delphi to ORACLE direct access Ramtin wrote: Quote: Hi Field editor adds TMemoField for "ntext" SQL type column, but added field dosn't support Unicode.

It probably was you who told me about a year ago that dbExpress doesn't.
