       Write a character via a code converter. The mconv_putc() function writes character c to the buffer area
       or the stream that is currently bound to code converter converter. The encoder of converter is used to
       encode the character. The number of bytes actually written is set to the nbytes member of converter. The
       internal status of converter is updated appropriately.
