I have been looking at what's involved in migrating our product to
unicode.   While most issues have been successfully resolved, I
recently ran into a problem which raised further questions.

There are a number of points in our stored procedures where direct SQL
is employed.   This is used where the table name is only known at
runtime.   So this involves usage of EXECUTE IMMEDIATE; also the OPEN
... FOR construct for returning a cursor to a recordset.

The difficulty arises when I attempt to run direct SQL which refers to
a table name which is unicode.   The reason it's a problem is that
EXECUTE IMMEDIATE does not accept a unicode SQL command (ie N'SELECT *
FROM ...').   Unfortunately, neither can I pass in the table name as a
parameter with the USING clause - Oracle doesn't allow this for table
names.   Meaning that in effect any table name I pass in has to be
coerced into an ANSI string.   I'd prefer not to mandate Roman script
to, say, a Chinese customer if I don't have to.

All of which raised another question:  does Oracle support unicode
table or column names?   I've done some searching on this and been
unable to arrive at a definite conclusion.

I'd be much obliged if someone could shed some light on this for me.
The Oracle versions of interest are 9.2 and later.

Thanks in advance,
