Writes chars from a <code>StringBuffer</code> to bytes on an
<code>OutputStream</code> using the specified character encoding.

This method uses {@link String#getBytes(String)}.

@param data     the <code>StringBuffer</code> to write, null ignored
@param output   the <code>OutputStream</code> to write to
@param encoding the encoding to use, null means platform default
@throws NullPointerException        if output is null
@throws IOException                 if an I/O error occurs
@throws UnsupportedCharsetException thrown instead of {@link UnsupportedEncodingException} in version 2.2 if the encoding is not
supported.
@since 1.1
@deprecated replaced by write(CharSequence, OutputStream, String)
