[alsoumahi alBatal]

Hi experts , I have converted my database to utf8 and collate is utf8_general_ci and also the table (it is utf8 , collate utf8_general_c)including all the fields(utf8 , collate utf8_general_c)
that contain Arabic characters , but when I display the values using mysqlWorkBench , it display ??? with the same number characters of Arabic word , how to show Arabic word
I think there is something missing

thanks in advance

What are you displaying the output on? Some DOS command line windows cannot support non-European characters.
