#24325 — Unicode >16 Bit JTextPane etc..

Dear All,

I tried a couple of fonts, but none of
these fonts were able to display the
Unicode 120000 (decimal).

I supplied the two surrogate pairs
D835 and DCC0. The JTextPane etc.. show
a single box, so that I assume the
code point is recognized.

What is wrong?

Bye

P.S.: My browser (mozilla) easily
shows the Mathematical Script Small K
which corresponds to the code point.

The white box is shown on Windows. On the
Mac some chinese or so is shown. But both
don't show Mathematical Script Small K.

What's a 16 bit JTextPane?
If you'll give a small demo code I'll try it
on Debian Squeeze and Windows 7,8, several JDK versions available.
Mathematical Script Small K shows up in gedit and a Mozilla browser here.

I believe the topic is to be read as "a unicode symbol above 16 bit in a
regular JTextPane".

The proper terminology is "non-BMP character", such as what exists in my 
 From header.

Sorry, too much trouble for me to wrap into compilable block.

Wow! Really?

import javax.swing.*;

public class SmallDemo {

   private JFrame frame = new JFrame("A Small Demo");
   private JTextPane textpane = new JTextPane();

   public SmallDemo() {
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     textpane.setText("\uD835\uDCC0");
     frame.add(textpane);
     frame.pack();
     frame.setVisible(true);
   }

   public static void main(String[] args) {
     SwingUtilities.invokeLater(new Runnable() {

       @Override
       public void run() {
         SmallDemo demo = new SmallDemo();
       }
     });
   }
}

Works here. You're welcome.

Same here [little white square] running (Fedora 18 fully patched on 
Friday, PAE kernel, Java 1.6.0_45).

Hmm. Shrugs. Java 1.7.0_21, Debian 6.0.7 works here [Mathematical Script 
Small K].

Just to be sure I was seeing what I was looking at, I've added:
...
textpane.setFont(new Font("Dialog", Font.PLAIN, 60));
textpane.setText("\uD835\uDCC0\uD835\uDC9C\uD835\uDC9E\uD835\uDC9F");
...

Yep. a Mathematical Script kACD.

This ends up printing Cambria Math for the font name on my system.

Thank you very much.
This is very interesting.
Didn't use canDisplay() so far.

Doesn't give something useful on Mac.

I get for (note the not before the canDisplay()):

     public static void main(String[] args) {
         Font[] allFonts = 
GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();
         for (int i = 0; i < allFonts.length; i++) {
             Font font = allFonts[i];
             if (!font.canDisplay(120000))
                 System.out.println("font=" + font.getFontName());
         }
     }

The following list:

font=Lucida Bright Demibold
font=Lucida Bright Demibold Italic
font=Lucida Bright Italic
font=Lucida Bright Regular
font=Lucida Sans Demibold
font=Lucida Sans Regular
font=Lucida Sans Typewriter Bold
font=Lucida Sans Typewriter Regular

But every font not on the above list, does erroreously
display some chinese character instead of the math symbol.

The fonts on the above list, on the other hand seem
to show a white box on the Mac.

Bye


P.S.: I am using 1.7.0_15. Let me try a newer version.

I don't see the character rendered with the expected glyph by my 
side, but I see a single rectangle box rendered which deems the text 
component is doing its job right by interpreting the surrogate pair 
as a single character.

Using "Symbola" or "Cambria Math" which appear to contain glyph for 
the character on my system:

     textpane.setFont(new Font("Symbola", Font.PLAIN, 24));

I see the character all right now, too.  I use an utility called 
"BabelMap" to find and analyze fonts under Windows.
