Another interesting question would be whether LO makes it too easy to
create a document with PUA instead of "proper" characters (by
deceivingly offering PUA characters in "Insert - Special Character...",
say), but looking at
<https://bugs.documentfoundation.org/show_bug.cgi?id=103944> that bug
.doc at least is presumably created with something else?
