       The  getwchar()  function  is  the wide-character equivalent of the getchar(3) function.  It reads a wide
       character from stdin and returns it.  If the end of stream is reached, or if ferror(stdin) becomes  true,
       it returns WEOF.  If a wide-character conversion error occurs, it sets errno to EILSEQ and returns WEOF.

       For a nonlocking counterpart, see unlocked_stdio(3).

       getwchar - read a wide character from standard input

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

       It  is  reasonable  to expect that getwchar() will actually read a multibyte sequence from standard input
       and then convert it to a wide character.

       The getwchar() function returns the next wide-character from standard input, or WEOF.
