Hi RGB
Our AIX editor can not able to edit GB2312 code, I update the text
string with byte value. It is OK ?
Since you already had a temp.txt file you could have just commented-out
the writeFile() call.
I didn't so I used Java to create one - you don't really need to do this
if you are certain that your temp.txt contains the characters in GB2312
encoding.
But see below ...
java GB2312Bytes
Change Terminal Emulation to Host charcter to GB2312., the output as
below
Writing =E6=B5=8B=E8=AF=95 to temp.txt
3f3f3f3f0a
od -ct x1 temp.txt
0000000 ? ? ? ? \n
3f 3f 3f 3f =
0a
0000005
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;
public class GB2312Bytes {
public static void main(String[] args) {
String fileName = "temp.txt";
String text = new String( new byte=
[] {
(byte) 0xb2, (byte) 0xe2 , (b=
yte) 0xca , (byte) 0xd4
Firstly, you should use Unicode escapes to insert unicode characters.
Secondly you should use Unicode code-points not GB2312 code points, this
is because Java Strings are Unicode strings (in UTF-16 encoding)
See <http://www.herongyang.com/gb2312/ug_map_24.html> 8BD5 CAD4 =E8=AF=95=
and
<http://www.herongyang.com/gb2312/ug_map_15.html> 6D4B B2E2 =E6=B5=8B
So use
String text = "\u6d4b\u=
8bd5";
When you later write this Unicode String data to a file using GB2312
encoding, Java will translate the Unicode code-point to the GB2312 code
point.
Also remember that Unicode is much bigger than GB2312, Java can only
perform this conversion if the Unicode code points are for characters
that are within the GB2312 character set. Unicode code points b2e2 and
cad4, that you specified) are actually Korean Hangul characters that are
not not in GB2312 and so are translated to "?".
});
writeFile(fileName, text, "GB2312");
System.out.println(fileAsHex(fileNam=
e));
}
private static void writeFile(String fileName, Str=
ing text,
String encoding) {
System.out.println("Writing '" + tex=
t + "' to " + fileName);
PrintWriter pw;
try {
pw = new PrintWriter=
(fileName, encoding);
pw.println(text);
pw.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (UnsupportedEncodingExceptio=
n e) {
e.printStackTrace();
}
}
private static String fileAsHex(String fileName) {
StringBuilder sb = new StringBuild=
er();
FileInputStream in = null;
try {
in = new FileInputSt=
ream(fileName);
int c;
while ((c = in.read(=
)) != -1) {
0x10) {
sb.append("0");
d(Integer.toHexString(c));
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (in != null) {
try {
=
in.close();
(IOException e) {
e.printStackTrace();
}
}
}
return sb.toString();
}
}

Thank . Rewrite the code, Output as below.
My JCreator Can not display GB2312 Code.
Writing '??' to temp.txt

Process completed.
