How to create afile of Unicode file format

Hi,

See the Code Below,

It is a Frame which shows you all unicode characters.

I think it will be help you.

Avdhut.

==========================================

import java.applet.*;

import java.awt.*;

import java.awt.event.*;

/**

* This program displays Unicode glyphs using user-specified fonts

* and font styles.

**/

public class UnicodeDisplay extends Frame implements ActionListener

{

int page = 0;

UnicodePanel p;

Scrollbar b;

String fontfamily = "Serif";

int fontstyle = Font.PLAIN;

/**

* This constructor creates the frame, menubar, and scrollbar

* that work along with the UnicodePanel class, defined below

**/

public UnicodeDisplay(String name) {

super(name);

this.setLayout(new BorderLayout());

p = new UnicodePanel();// Create the panel

p.setBase((char)(page * 0x100));// Initialize it

this.add(p, "Center");// Center it

// Create and set up a scrollbar, and put it on the right

b = new Scrollbar(Scrollbar.VERTICAL, 0, 1, 0, 0xFF);

b.setUnitIncrement(1);

b.setBlockIncrement(0x10);

b.addAdjustmentListener(new AdjustmentListener() {

public void adjustmentValueChanged(AdjustmentEvent e) {

page = e.getValue();

p.setBase((char)(page * 0x100));

}

});

this.add(b, "East");

// Set things up so we respond to window close requests

this.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {

UnicodeDisplay.this.dispose();

System.exit(0);

}

});

// Handle Page Up and Page Down and the up and down arrow keys

this.addKeyListener(new KeyAdapter() {

public void keyPressed(KeyEvent e) {

int code = e.getKeyCode();

int oldpage = page;

if ((code == KeyEvent.VK_PAGE_UP) || (code == KeyEvent.VK_UP)) {

if (e.isShiftDown()) page -= 0x10;

else page -= 1;

if (page < 0) page = 0;

}

else if ((code == KeyEvent.VK_PAGE_DOWN) || (code==KeyEvent.VK_DOWN)) {

if (e.isShiftDown()) page += 0x10;

else page += 1;

if (page > 0xff) page = 0xff;

}

if (page != oldpage) { // if anything has changed...

p.setBase((char) (page * 0x100)); // update the display

b.setValue(page);// and update scrollbar to match

}

}

});

// Set up a menu system to change fonts. Use a convenience method.

MenuBar menubar = new MenuBar();

this.setMenuBar(menubar);

menubar.add(makemenu("Font Family",

new String[] {"Serif", "SansSerif", "Monospaced"},

this));

Hi,

I wrote once an editor (in Java) with user-defined encoding. I tested it with following encodings: ISO-8859-1, ISO-8859-2, UTF-16. The last one is that you were asking for: 16 bit Unicode.

I can read and write files with international characters. In order to type this characters in this editor you must have an apropriate keyboard driver (standard in Windows).

If you want just quick create some files I can send you the program per mail. On you own risk ;-)

Send me your e-mail address if you want it.

Regards,

Martin

Hi, my name is Urs

I am looking for this editor too, I mean, the thing I'm looking for is to write a file in Unicode-16 which I can open as a "normal" file in an editor such as word which supports unicode.

I write a program for historians, store the information in a xml-file and cause they mix in some cases different languages, they also use different special characters. Thank you very much for your help, Urs
