       The  putwchar() function is the wide-character equivalent of the putchar(3) function.  It writes the wide
       character wc to stdout.  If ferror(stdout) becomes true, it returns WEOF.  If a wide character conversion
       error occurs, it sets errno to EILSEQ and returns WEOF.  Otherwise, it returns wc.

       For a nonlocking counterpart, see unlocked_stdio(3).

       putwchar - write a wide character to standard output

       The behavior of putwchar() depends on the LC_CTYPE category of the current locale.

       It is reasonable to expect that putwchar() will actually write the multibyte  sequence  corresponding  to
       the wide character wc.

       The putwchar() function returns wc if no error occurred, or WEOF to indicate an error.
