They want to send unambiguous It is no more no less secure than ascii. What you sign is just a given flow of bytes; the screen representation is up to the computer. There is no way to be sure of the computer equipment at the other end. The only thing you can certify, sign, is what you send: a flow of bytes. > What if the software we are using would have built in sanity checks > using reversible algorithms to convert the bitstream to a view, and > convert it back to check if we get back the same stream? What I don't understand the usefulness of that. Also, rendering is, by nature, always different: you change the width of your window and the text will wordwrap and linewrap at different places. > I just asked #1 at unicode consortium but there is a communication > breakdown and I unsubscribed.
