No I don't expect the server to match it, since it is deleted. All I am
saying is that the assumption that has been stated here many times that "an
application that uses a former version of Nameprep to speak to a server
using a later one has nothing to worry about because it just passes all
unassigned codepoints (from its former Nameprep perspective) to the server"
is not true. If that assumption is old / has been revised then I am just
wasting your bandwidth :)
