I don't think your Java code does what you think it does. You should read
some more about how Java handles string encodings. Here is a method I wrote
some years ago that might also help you. It converts streams, not strings,
but what you need should be pretty close (and simpler):
/**
* Interprets in according to encIn, and converts it to encOut,
* writing to out. Allocates buffer for the buffer size.
*
* @param encIn The input encoding.
* @param encOut The output encoding.
* @param in The data to convert.
* @param out Where to send the converted data.
* @param buffer The size of the buffer or 0 for the default.
*
* @throws IOException
*/
public void run(String encIn, String encOut, InputStream in, OutputStream
out, int buffer) throws IOException {
Reader r = null;
Writer w = null;
int len;
char[] b;
try {
if (buffer > 0) {
r = new BufferedReader(new InputStreamReader(in, encIn), buffer);
w = new BufferedWriter(new OutputStreamWriter(out, encOut), buffer);
} else {
r = new BufferedReader(new InputStreamReader(in, encIn));
w = new BufferedWriter(new OutputStreamWriter(out, encOut));
buffer = DEFAULT_BUFFER_SIZE;
}
b = new char[buffer];
while ((len = r.read(b, 0, buffer)) != -1) {
w.write(b, 0, len);
}
} finally {
try {
if (r != null) r.close();
} finally {
if (w != null) w.close();
}
}
}
Btw, none of this has anything to do with Postgres. :-)
