Re: using 8 bit ascii

Is it JDBC driver or another interface that says it cannot support the
Unicode values when you insert? What is the exact error message you get?

If you use for example ODBC and insert Latin-1 characters in a Unicode
db, things will go wrong. You can issue the following statement:
SET CLIENT_ENCODING TO 'LATIN1';
This will tell postgresql to expect latin1 characters. Postgresql will
then automatic convert to correct character set if necessary.

The JDBC driver will always operate in UNICODE mode, so it should not
have any problems with either Latin1 nor unicode databases.

I use JDBC driver with both Latin1 and Unicode databases with no
problems. I also use psql for some scripts, but I have ISO-8859-1
terminal, so I execute the above query first.
(Actually I have "\encoding LATIN1" in my .psqlrc file).

triedconverting the data as a text file and everything.  Nothing has worked there.  With odbc using access for example
Ican pull the 8 bit characters out just fine from the same database.  So why can I not using postgres jdbc?
