-/**
- * This class permits a <code>String</code> to be read as an input stream.
- * The low eight bits of each character in the <code>String</code> are the
- * bytes that are returned. The high eight bits of each character are
- * discarded.
- * <p>
- * The mark/reset functionality in this class behaves differently than
- * normal. The <code>mark()</code> method is always ignored and the
- * <code>reset()</code> method always resets in stream to start reading from
- * position 0 in the String. Note that since this method does not override
- * <code>markSupported()</code> in <code>InputStream</code>, calling that
- * method will return <code>false</code>.
- * <p>
- * Note that this class is deprecated because it does not properly handle
- * 16-bit Java characters. It is provided for backwards compatibility only
- * and should not be used for new development. The <code>StringReader</code>
- * class should be used instead.
- *
- * @deprecated
