The
btowc() function shall determine whether
c constitutes a valid
(one-byte) character in the initial shift state.
The behavior of this function shall be affected by the
LC_CTYPE category
of the current locale.
The
btowc() function shall return WEOF if
c has the value EOF or
if
(unsigned char) c does not constitute a valid (one-byte)
character in the initial shift state. Otherwise, it shall return the
wide-character representation of that character.
