it would be nice to allow François to enter his name like that, rather than

Can we use any binary value between 0-255 for each character? If so, I
would also like to propose that we change the "unreserved" production
to allow any character between 0-255, excluding % and @ (since those have
special meanings). What do you think?<o:p></o:p></span></font></p>

raises another question: how do we enforce the rule that names are not case
sensitive. That would suggest that for any given character set within
unicode, the manufacturer will have to know which characters are the upper and
lower case ranges. Is this desirable to recommend? I like names
that are not case sensitive, but this might be overly complex to try to
do. It would make internationalization of a Gatekeeper, for example,
much more difficult than it is today-- I suspect some vendors will not go
through the effort.</span></font></span><font color=black><span
