getwchar - read a wide character from standard input
wint_t getwchar (void);
The getwchar function is the wide-character equivalent of the getchar
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.
The getwchar function returns the next wide-character from standard
input, or WEOF.

The behaviour of getwchar depends on the LC_CTYPE category of the current
It is reasonable to expect that getwchar will actually read a multibyte
sequence from standard input and then convert it to a wide character.
