wctob - try to represent a wide character as a single byte
#include <wchar.h>
int wctob(wint_t c);
The wctob() function tests whether the multibyte representation of
the wide character c, starting in the initial state, consists of a
single byte. If so, it is returned as an unsigned char.
Never use this function. It cannot help you in writing
internationalized programs. Internationalized programs must never
distinguish single-byte and multibyte characters.
The wctob() function returns the single-byte representation of c, if
it exists, of EOF otherwise.
For an explanation of the terms used in this section, see
attributes(7).

POSIX.1-2001, POSIX.1-2008, C99.
The behavior of wctob() depends on the LC_CTYPE category of the
current locale.
This function should never be used. Internationalized programs must
never distinguish single-byte and multibyte characters. Use either
wctomb(3) or the thread-safe wcrtomb(3) instead.
