I'm hoping I've got a config setting wrong somewhere, but I've been stuck with a client issue, that I've found wasn't the application that I'm supporting. I've boiled it down to the following:

If I run the following SQL from either a SQL or Command window

select 'Ş' from dual;

The results window displays

S

If I run this from Oracle SQL Developer, it displays correctly.

Is there something I need to change to make the display correct?
