If I understand correctly, you want to save arabic text into a SQL Server Database field.  Am I right?  Then write the below code into SQLPreview Event of that particular datawindow

n_dwr_string	lnv_string

Choose case sqltype
	Case PreviewInsert!
		sqlsyntax = lnv_string.of_globalreplace(sqlsyntax,"( '", "( N'")
		sqlsyntax = lnv_string.of_globalreplace(sqlsyntax ,", '", ",N'")
		this.setsqlpreview(sqlsyntax)
		
	Case PreviewUpdate!, PreviewDelete!
		sqlsyntax = lnv_string.of_globalreplace(sqlsyntax ,"= '","= N'")
		this.setsqlpreview(sqlsyntax)
End Choose

It will prefix the character 'N' before inserting the data into the column.

HTH

Happiness Always

Long ll_Start, ll_OldLen, ll_NewLen

String ls_Source



//Check parameters

If IsNull ( as_source ) or IsNull ( as_old ) or IsNull ( as_new ) or IsNull ( ab_ignorecase ) Then

string ls_null

SetNull ( ls_null )

Return ls_null

End If



//Get the string lenghts

ll_OldLen = Len ( as_Old )

ll_NewLen = Len ( as_New )



//Should function respect case.

If ab_ignorecase Then

as_old = Lower ( as_old )

ls_source = Lower ( as_source )

Else

ls_source = as_source

End If



//Search for the first occurrence of as_Old

ll_Start = Pos ( ls_Source, as_Old )



Do While ll_Start > 0

// replace as_Old with as_New

as_Source = Replace ( as_Source, ll_Start, ll_OldLen, as_New )



//Should function respect case.

If ab_ignorecase Then

ls_source = Lower ( as_source )

Else

ls_source = as_source

End If



// find the next occurrence of as_Old

ll_Start = Pos ( ls_Source, as_Old, ( ll_Start + ll_NewLen ) )

Loop



Return as_Source





You can use the above function to replace values.

What DataWindow Control method are you using to save the Arabic data as text?

The SaveAs and SaveAsFormattedText methods support an optional encoding argument that is use to specify the desired encoding. I believe that you must use Unicode16LE encoding to faithfully save the Arabic text.

Consult PB Help for these methods for details.

Best regards, John
