Need help on Unicode (GURMUKHI) in java

Expand Post »

Hello everyone,

Im trying to write Punjabi (Gurmukhi) by Unicode. I have the Unicode code point of all character and Code Block is Gurmukhi.

java Syntax (Toggle Plain Text)
System.out.prinln("\u0A73")
System.out.prinln("\u0A73")

u0A73 = GURMUKHI URA = ੳ

but its showing "?".

then i tried with PrintStream

java Syntax (Toggle Plain Text)
String unicodeMessage = "\u0A73";
		   try {
			   PrintStream output = new PrintStream(System.out, true, "UTF-8");
					output.print(unicodeMessage);
				} catch (UnsupportedEncodingException e) {
					e.printStackTrace();
				}
String unicodeMessage = "\u0A73";
		   try {
			   PrintStream output = new PrintStream(System.out, true, "UTF-8");
					output.print(unicodeMessage);
				} catch (UnsupportedEncodingException e) {
					e.printStackTrace();
				}

now its showing "à©³".

Tried with UTF-16 and UTF-32 too.

so, i decided to post here for help. can anyone help me to sort out this problem ?

Thanks in advance.

Re: Need help on Unicode (GURMUKHI) in java

There is as such no problem with your code; IMO the fault lies with the incompetence of the shell to render fonts correctly. I assume you are on a windows box? Anyways, this is just a rendering issue. Maybe a little more background on what you are trying to achieve here would be required to offer some advice.

Anyways, to mess around with code points and to get a feel of how the characters looks, try this sample snippet which creates an HTML document 'test.html'.

Java Syntax (Toggle Plain Text)
// Error handling and best practices omitted for brevity
 
public class HtmlTester {
 
  private final static String HTML = 
  "<html><head><META HTTP-EQUIV=\"Content-Type\" " +
      "CONTENT=\"text/html; charset=UTF-8\"></head><body><div>{0}" +
      "</div></body></html>";
 
  public static void main(final String[] args) throws Exception {
    testIt();
  }
 
  public static void testIt() throws Exception {
    String toWrite = MessageFormat.
      format(HTML, String.valueOf("\u0A72 \u0A73 \u0A74"));
    writeData(toWrite, new File("test.html"));
  }
 
  public static void writeData(String s, File f) {
    try {
      BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
          new FileOutputStream(f), "utf-8"));
      out.write(s);
      out.flush();
      out.close();
    } catch(Exception e) {
      e.printStackTrace();
    }
  }
 
}
// Error handling and best practices omitted for brevity

public class HtmlTester {

  private final static String HTML = 
  "<html><head><META HTTP-EQUIV=\"Content-Type\" " +
      "CONTENT=\"text/html; charset=UTF-8\"></head><body><div>{0}" +
      "</div></body></html>";

  public static void main(final String[] args) throws Exception {
    testIt();
  }

  public static void testIt() throws Exception {
    String toWrite = MessageFormat.
      format(HTML, String.valueOf("\u0A72 \u0A73 \u0A74"));
    writeData(toWrite, new File("test.html"));
  }

  public static void writeData(String s, File f) {
    try {
      BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
          new FileOutputStream(f), "utf-8"));
      out.write(s);
      out.flush();
      out.close();
    } catch(Exception e) {
      e.printStackTrace();
    }
  }

}

The gurmukhi characters are displayed correctly since I guess browsers have their own font rendering engine.

Hello,

Thanks for reply,
Actually, im creating a virtual Punjabi keyboard. On swing components, I used setFont() method and working perfectly. But i also need to display it on Console.

Im using Windows Vista and Eclipse IDE.

Im still on it, hope to the solution soon.

Thanks again!

Re: Need help on Unicode (GURMUKHI) in java

If you plan on viewing the output on Eclipses's console, it shouldn't be that big a problem. Try following the advice in this post.

But if you are stuck with windows console, then there isn't a reliable / sure shot way of getting it to work. Many have suggested setting the code page to 65001 though I am not very sure whether it works in all cases.

Let me know if the above suggested fixes work in your case. Best of luck for your project; hoping to see it on sourceforge. ;-)

So, were you trying it on Eclipse or windows console? BTW, bump this thread when your project is completed. :-)

I meant post a reply here once it is completed and up on sourceforge, so that I can get a notification; it might interest the kids new to Java.
