You didn't provide any information on any of the software in use, but any modern
software should be able to handle this, IF you've configured the database correctly.
What character set did you establish for the database?
What NLS_LANG have you defined on the clients?
Have you verified that you can use the desired character set from SQL*Plus on
both the server and from clients?
You probably want to ask this question in an Oracle forum. If you do, be sure
to provide complete software version information (e.g., "Oracle 11.2.0.3.6 server
with 11.2.0.3.0 client")
