I've searched the archives but haven't found any useful information.

I'm trying to change the encoding of the default 'System.out' output
stream so I could see some international characters in the text console.

I'm trying this on Win2000:

public class EncodingTest {

public static void main(String[] args) {
String cyrStr = "\u0430\u0431\u0432\u0433\u0434\u0435";
String latStr = "\u00E0\u00E1\u00E2\u00E9\u00EA\u00EB";

System.out.println(System.getProperty("file.encodi ng"));
System.out.println(cyrStr);
System.out.println(latStr);
JOptionPane.showMessageDialog(null, cyrStr + "\n" + latStr);
System.exit(0);
}

}

So my default encoding seems to be "Cp1251" (because of my regional
settings) and on the command prompt I type:

C:\>chcp 1251
C:\>java EncodingTest

and I get:

Cp1251
абвгде
??????

then I want to see the latin supplement characters and I type:

C:\>chcp 1252
C:\>java -Dfile.encoding=Cp1252 EncodingTest

and I get:

Cp1252
Ã*áâãäå
??????

So is it possible to change the encoding of the default 'System.out'?

Redirect "System.out" to a *PrintStream*, so that you can change the
encoding.

#define User "Yu.Song"

#define Warwick "warwick.ac.uk"
int main() {
printf("Yu Song's E-mail: %s%c%s", User, At, Warwick);
return 0;}

If you look at the source code, you'll see that the System.out is final,
so you can't change that without recompiling the library (and I
wouldn't suggest doing that.) Here's what I came up with.

import java.io.*;

public class test {
public static void main(String[] args) {

PrintStream ps = null;

try {
ps = new PrintStream(System.out, true, "ISO-8859-1");
} catch (UnsupportedEncodingException error) {
System.err.println(error);
System.exit(0);
}

ps.println("\u00E0\u00E1\u00E2\u00E9\u00EA\u00EB") ;
}
}

where "ISO-8859-1" is replaced by whatever character encoding you want.

Lookup the type of System.out: it is a PrintStream, which is a subclass
of OutputStream. OutputStreams are _byte_ streams. There is no
relevant concept of a character encoding. You can, however, do this:

PrintWriter out =
new PrintWriter(
new OutputStreamWriter(System.out, "Cp1251"));

[You will need to be prepared to handle an UnsupportedEncodingException.]

Thereafter write to your PrintWriter out, instead of directly to
System.out, and you should be in good shape. [Note that I make no
representation as to the console's ability to correctly display the
resulting byte stream; I assume you have that under control.]

Huh... Thank you you, John (and thank you to John Davidson, too).

You know guys, this was the first thing I've tried but in this form:

Writer out = new OutputStreamWriter(System.out, "ISO-8859-1");
out.write("\u00E0\u00E1\u00E2\u00E9\u00EA\u00EB");

and it just don't work (no output at all), that's why I've decided
to post. But then using:

PrintStream out = new PrintStream(System.out, true, "ISO-8859-1");
out.println("\u00E0\u00E1\u00E2\u00E9\u00EA\u00EB" );

does it just fine - thank you, again.

My code which is simply casting the ascii character to get decimal value and it is working properly. For example:

publicstaticvoid main(String[] args) {
char character = 'A';
int intChar = (int) character;
System.out.println("Decimal Value is " + intChar);
}

Which returns me correct output as below:
Decimal Value is 65

Above code is working fine when characters range is from 0 to 127 (US-ASCII). But when I am trying to get the decimal value for extended ascii characters it
returns me wrong decimal number. For example

publicstaticvoid main(String[] args) {
char character = 'Š';
int intChar = (int) character;
System.out.println("Decimal Value is " + intChar);
}
Which returns me incorrect output as below:
Decimal Value is 352

Instead it should return 138 as decimal value. 352 is the Unicode value for character 'Š' but I am expecting 138 which is correct value. Please help me to achieve this.
