Re: Sybase connection error: JZ0IB: default charset of roman8 doesn't map

You seem to be without options when attempting to connect with *any*
Java application to a Sybase server with charset = roman8 :

   10106   270704   jConnect now kills the connection when the
                    server's default charset is unsupported in Java
                    (and the client has not made a specific request
                    for a charset).  When the client does not request
                    a specific charset, jConnect will attempt to use
                    the server's default charset. However, there are
                    cases where the server charset does not map to
                    Java (because there is no corresponding converter
                    in Java -- an example would be the roman8
                    charset).   Previously, jConnect would allow the
                    Connection to be made, but the connection would be
                    unusable, as all further communications with the
                    server would result in an exception.  jConnect now
                    throws at JZ0IB exception and does not allow the
                    connection to be made.

Specifically the phrase:

"However, there are cases where the server charset does not map to
Java (because there is no corresponding converter in Java -- an
example would be the roman8 charset)."

Anyone with specific knowledge of charset support in Java want to
comment on this apparent short-coming?
