When Java reads a string from a byte stream, it converts platform-related bytes into platform-independent Unicode strings. During output, Java will convert the Unicode string to the byte stream related to the platform. If a Unicode character does not exist on a platform, ′? ′. For example, in Japanese windows, Java reads a "shift_jis" encoded
