The following bug has been logged online:

Bug reference:      2693
Logged by:          Delight Chen
Email address:      delight@nineder.com
PostgreSQL version: 8.1.4
Operating system:   Red Hat Enterprise Linux ES release 4 (Nahant) Kernel
2.6.9-5.ELsmp on an x86_64
Description:        Abut SQL ASCII through JDBC
Details:

I tried to install postgresql 8.1.4
Initdb with SQL_ASCII is work.
Create table is correct.
Insert Big5 text data correctly.
Try to view through /usr/local/pgsql/bin/psql and it's correct.
But when I try to query throught JDBC Driver, it always says "invalid byte
value for encoding"


And I tried another version 7.3.3 of postgresql.
Do all of thing above I metioned, and check it.
Finally I check data throught JDBC Driver, it's work correctly.


I think it's a bug for 8.1.4, so I report to you.
