Generating Nepali Unicode Sequence For Characters

While I was working on a translation project for myself, I got into some localization phase. Since Nepali Characters are represented in unicode (u09xx), it was difficult to write Strings in this form. So, I wrote this class called unicode generator, where the input to this is common english keys used to write in nepali using romanized keyboard layout. This means, if you are going to write ‘Kushal’ in nepali, you would key in ‘kuSl’. Now, when you pass ‘kuSl’ to the format method of the following class, you will retrieve string like ‘u09xxu00xxu00xxu00xx’ where xx will be replaced by some number for correct characters. For instance, for the work ‘ka’ in Nepali, u0915 is the unicode. You can use this string to be displayed in GUI’s.

	 * Usage Example
	public static void main(String args[]) {
		UnicodeConverter generator = new UnicodeConverter("np");
		 * Usage: If you want to print mero naam Kushal ho, you would be keying
		 * in the following for romanized unicode keyborads mero nam kuSl ho
		// String test = generator.format("raz/q/riy"); // Rastriya
		String test = generator.format("mero nam kuSl ho");
		JOptionPane.showMessageDialog(null, test);

    This approach uses less memory:

    public static class SizeCounter implements FileFilter
    private long total = 0;
    public SizeCounter(){};
    public boolean accept(File pathname) {
    if ( pathname.isFile()) {
    } else {
    return false;
    public long getTotal()
    return total;

    private static long getFileOrDirectorySize(File file) {
    SizeCounter counter = new SizeCounter();
    return counter.getTotal();
