Thanks for your comments, Michael. There are a few things to remember here.
First, according to the recommendations, when characters are restricted it
doesn't mean that you can't use them; it means that you either have to use a
looser restriction level, or you would get a one-time alert. It is not
simply a list of characters; reading the lists in isolation from the text
would not provide enough information to see how they are to be used. You may
also be looking at older versions: see
Second, and most importantly, the data and recommendations are not by any
means set in stone. This is the initial version, and we expect it to be
refined over time, in consultation with other groups -- particularly the
IETF. You have plenty of opportunity to provide feedback for future
versions. Best is, of course, to get your feedback in early in the cycle ;-)
