You could use the DUMP() function to see what is actually stored in the database.

If you can get Euro signs from a LATIN-1 database, it is an indication that you are a victim of the problem I mentioned upthread, namely that Oracle doesn't check your input if client and server character set are identical.

You probably have the Euros stored as hex 0x80 if the client is a Windows machine (make sure with DUMP).

You will get the 0x80 back as long as client and server character set stay the same, but there is no other setting for the client character set that will deliver anything meaningful.

That is because you have bad data in your database, and they cannot be converted from LATIN-1 to anything. Essentially it is a case of user induced data corruption.

You can either
1) stick with LATIN-1 on both server and client and pray that nobody will

   ever enter characters in a different encoding and that you will never    have to access the database from a non-Windows system. 2) if you are sure that all bogus characters are actually WE8MSWIN1252,

   you could try to change the database character set.
