Formula to show non englissh charactersb from clob in crystal report

Hi

I am using the database Oracle 11g with a field clob in one of the table that i want to show in the crystal report

But the problem is when i put the clob field in crystal report it is outputting the results perfectly for English characters but not for the Arabic ones and returning the string like (¿¿¿¿ ¿¿¿¿ ¿¿¿ ¿¿¿¿ ¿¿¿¿ ¿¿¿ ¿ ¿¿¿¿¿ ¿¿¿)

so is there any way to show the arabic (non english) characters perfectly on crystal report with clob field
