In 11gR2, sometimes it's possible to see the character set in v$session_connection_info.client_charset:

SQL> select client_charset, count(*)
  2 from v$session_connect_info
  3 where sid in (select sid from v$session)   4 group by client_charset;

CLIENT_CHARSET COUNT(*)
-------------- ------------

UTF8                    159
Unknown                  24
AL32UTF8                  4

I added the "where sid in" part because some sessions in v$session_connect_info are invisible (recursive etc).

Most garbage character problems can be easily diagnosed with SQL trace.

By the way, on our RAC, we always use Java OCI (thick) client because the thin client can't do server side failover or load balance controlled by services.
