This Method is to read the unicode file, and it will return the String

public String readUnicodeFile(String filename) {
    StringBuffer buffer = null;
    InputStream is = null;
    InputStreamReader isr = null;
    try {
        Class c = this.getClass();
        is = c.getResourceAsStream(filename); 
        if (is == null) throw new Exception("File Does Not Exist");
        isr = new InputStreamReader(is,"UTF8"); 
        buffer = new StringBuffer();
        int ch;
        while ((ch = isr.read()) > -1) {
            buffer.append((char)ch);
            if (isr != null) isr.close(); 
        }
    }catch (Exception ex) {
        System.out.println(ex);
    }
    return buffer.toString(); 
}
