How do I display the Euro symbol ("€") in SQL*Plus?
To check if the current font contains the Euro sign, enter the Euro sign's decimal number equivalent in SQL*Plus, Alt+0128. If it appears correctly, the chosen font contains the Euro sign, otherwise you need to try another font.

You can use the Windows Character Map utility to view the characters available in a font. Character Map also shows the decimal number equivalent for extended ASCII characters. You access the Character Map utility by selecting Start, Programs, Accessories and then clicking Character Map.

Thanks - I'm using Arial which contains the euro.  I populate a temporary table thus;

insert into <table name> select chr(14844588) from dual;
insert into <table name> select chr(128) from dual;

I I dun up oracle programs > oracle > sqlplus

select * from <table name>

Unfortunately, no euro is displayed.  I can do it through unix and DOS.  Howewver....
