 * \details
 * 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());
