Insert byte[] into postgres text-field

Question

Hi,
i made some tries on using postgresql and jdbc, i noticed that
for some reason the postgres jdbc.driver does not convert
text from the db correct to UNICODE. The db is in ISO-8859-1.
So, i tried to write a workaround to this and was successfull
for reading data. The code is this:
try {
    String  sOrt   = null;
    InputStreamReader isString;
    BufferedReader bisString;
    ResultSet result =
        stmt.executeQuery( "select * from adresse.ort" );
    while( result.next() ) {
        isString = new InputStreamReader(
                            result.getBinaryStream( "ort" ),
                            "ISO-8859-1" );
        bisString = new BufferedReader( isString );
        sOrt = bisString.readLine();
...This works fine. Now i also wanted to but a correctly convertet
String in the db.
And i tried so:
try {
    String sOrt = "solal�";    // note the special german char �
    byte[] sOrt_ba = sOrt.getBytes( "ISO-8859-1" );
    pstmt = con.prepareStatement( "insert into adresse.ort " +
                                  "(ort, vorwahl_o, id_land) " +
                                  " values " +
                                  "(?, '00000', 1)" );
    pstmt.setBytes( 1, sOrt_ba );
    int sRows;
    sRows = pstmt.executeUpdate();
}but this sets not the correct character for the special char �
but instead puts the byte-value \366 into the db.
My question is as simple as the answer might be complex, what am
i doing wrong, and how can i accomplish this.

Answer 1

i found a solution for me, its not clean (to be sure its very ugly) but it works for the moment, if anyone has a better idea please tell. I will make the
following.
create a small plpgsql function like this.
CREATE FUNCTION jdbc_clean(text) RETURNS text AS'
    DECLARE
        ret text;
    BEGIN
        SELECT INTO ret replace($1, ''\\\\344'', ''�'');
        SELECT INTO ret replace(ret, ''\\\\366'', ''�'');
        SELECT INTO ret replace(ret, ''\\\\374'', ''�'');
        SELECT INTO ret replace(ret, ''\\\\337'', ''�'');
        RETURN ret;
    END;
' LANGUAGE 'plpgsql'and call this in my Java-method for every String i inserted or
updated in a seperate update query.
I have not written it for now, but i guess this will be working.
