What characters are valid in a Linux password?

I don't see anything in 'man passwd' to indicate any limit of the type
of characters it accepts.  In fact the less sane it is, the better it is
as a password.  The crypt() function uses certain characters as salt,
but it does not mention anything either about type of characters for the
entered password.
