The &func function determines if the next multibyte character in the
string pointed to by
.arg ch
is a null character or a valid lead byte followed by a null
character.
.im farparm
.desc end
.return begin
The &func function returns 1 if the multibyte character pointed to by
.arg ch
is a null character.
The &func function returns 2 if the multibyte character pointed to by
.arg ch
is a valid lead byte character followed by a null character.
Otherwise, the &func function returns 0.
