Unicode conversion

Most java programmers sooner or later face the problem of localization of the created products. And, despite the fact that the method of localization is described quite well, for example, you can refer to the manual at

static

// Returns hex String representation of char c

byte hi = ( byte ) (c >>> 8);

byte lo = ( byte ) (c & 0xff);

return byteToHex (hi) + byteToHex (lo);

}

class:

http://java.sun.com/docs/books/tutorial/i18n/text/example-1dot1/UnicodeFormatter.java

The program is a panel split into two parts (see Fig. 1).

Fig. one.

In the top panel, enter the text that you want to recode, while in the bottom panel we immediately get its counterpart in Unicode. For ease of copying, context menu handlers are added that are invoked using the mouse.

To handle keystrokes, keystroke and release listeners have been added to the source container, which call the transcoding method:

. . .

// Listeners for pressing and releasing keys

srcText.addKeyListener ( new java.awt.event.KeyAdapter () {

public void keyReleased (KeyEvent e) {

srcText_keyReleased (e);

}

public void keyTyped (KeyEvent e) {

srcText_keyTyped (e);

}

});

private void srcText_keyReleased (KeyEvent e) {

convertToUnicode ();

}

private void srcText_keyTyped (KeyEvent e) {

convertToUnicode ();

}

private void convertToUnicode () {

String source = srcText.getText ();

char [] ca = source.toCharArray ();

targetText.setText (convertChars (ca));

}

// Directly recoding

public String convertChars ( char [] array) {

StringBuffer s = new StringBuffer ();

for ( int k = 0; k <array.length; k ++) {

byte hi = ( byte ) (array [k] >>> 8);

if (hi! = 0) {

s.append ( "\ u" + UnicodeFormatter.charToHex (array [k]));

} else {

s.append (array [k]);

}

}

return s.toString ();

}
