    Perfectly legal.

    Only it does not stand for e acute, as far as unicode is involved it just
    stands for itself, for &#233;.

    Of course you are allowed to have agreements with your users about replacing
    &#233; by e acute or by whatever you want to replace it by.
    Just like you can agree with them to convert lower case to capitals.

    No. For those the situation is just the same as for the chars above 7F.
    Entities in an UTF-8 file stand for the chars they are composed of, not
    for the chars they denote.
