Hi,

Postgres 6.4.2 has multibyte support, so database can be
in one of several encodings. But the JDBC driver uses
for fetching data this method:
src/interfaces/jdbc/postgresql/ResultSet.java line 164:
return new String(this_row[columnIndex - 1]);

It means that not the database internal encoding, but 
the default encoding of client JVM will be used for
converting 8-bit characters to 16-bit UNICODE characters.

In postgres 6.5beta is the same code, so I think next
release will have the same bug.

Is it difficult to get the database encoding and use
it for converting bytes to Strings ? Is anybody planning
to do it ? If not, how can I do it ?

Martin
