     * The output stream contains chars with twice as many output
     * items as input items. For every complex input item, we produce
     * two output chars that contain the real part and imaginary part
     * converted to chars:
     *
     * \li output[0][n] = static_cast<char>(input[0][m].real());
     * \li output[0][n+1] = static_cast<char>(input[0][m].imag());
