NAME
       btowc - convert single byte to wide character

SYNOPSIS
       #include <wchar.h>

       wint_t btowc(int c);

DESCRIPTION
       The btowc() function converts c, interpreted as a multibyte sequence of length 1, starting in the initial shift state, to
       a wide character and returns it.  If c is EOF or not a valid multibyte sequence of length 1, the btowc() function returns
       WEOF.

RETURN VALUE
       The  btowc()  function returns the wide character converted from the single byte c.  If c is EOF or not a valid multibyte
       sequence of length 1, it returns WEOF.

CONFORMING TO
       C99, POSIX.1-2001.

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

       This function should never be used.  It does not work for encodings which have state,  and  unnecessarily  treats  single
       bytes differently from multibyte sequences.  Use the function mbtowc() instead.
