Properties.load method read one byte and convert it into unicode character.
There are some character encoding to support some languange which
consist of more than one byte. But the load method can be only applicable
to ascii character. It is hardcoded. We can't use this class for localization
like messages handling.

The following are the point of problem in the Properties class.

    public synchronized void load(InputStream in) throws IOException {
        in = Runtime.getRuntime().getLocalizedInputStream(in); <--- I guess this method
                                                                                                       became a obsolete one
                                                                                                       in 1.1

        int ch = in.read(); <--- read one byte.
        while (true) {
            switch (ch) { <--- deal with the read byte as unicode.
              case -1:
                return;

              case '#':
              case '!':
                do {
                    ch = in.read();
                } while ((ch >= 0) && (ch != '\n') && (ch != '\r'));
                continue;

              case '\n':
              case '\r':
              case ' ':
              case '\t':
                ch = in.read();
                continue;
