putwchar - write a wide character to standard output
#include <wchar.h> wint_t putwchar(wchar_t wc);
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).
The putwchar() function returns wc if no error occurred, or WEOF to indicate an error.

POSIX.1-2001, POSIX.1-2008, C99.
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.
