When I query for data that have arabic text in PL/SQL Developer, It is showed as question marks (????).
I am sure the data is correctly stored in DB because it shows on website properly, also on the server.
So I think it is a problem related to my PL/SQL Developer (v8.0.4.1514).
-
Is there any way to change how PL/SQL Developer shows/encodes arabic text?
-
How to check in what format/encoding the arabic text is stored?
My question might be missing some details, So Just ask me and also keep in mind that I am very beginner in PL/SQL and in SQL.
Thank you.

Answer
I found a solution (which might also work with other languages that shows as ‘????‘)
I changed the NLS_LANG in registry to AMERICAN_AMERICA.AL32UTF8
(I found 3 NLS_LANG‘s in registry, check with each one or just change them all like I did.)
then restarted PL/SQL developer, test a query and arabic text is showing normally.
Thank you all.
