>The strange thing here is the Str In. unixODBC obviously received 38 bytes, however, only 19 are printed, exactly the half it it. This fits: Only every second charcter of my connection string is shown here (I replaced the password characters with asteriks). It seems that Oracle is sending UTF-8, and unixODBC expects UTF-16, or vice versa. Is this a bug in Oracle or unixODBC? Are there any configuration settings in unixODBC where I can make unixODBC understand the connection string correctly?

Well, according to Oracle (the part that does the dg4odbc software, not 
their ODBC driver) its a bug in unixODBC. My view is they made the 
mistake of listening to Data Direct about what unicode should be like.
