Hello Roozbeh,

Many thanks for your comment. As far as I remember, currently ZNWJ is
dropped by nameprep without complaining. I think that if that leads to
problems as you describe above, we should very carefully reexamine
this decision. I have already told the nameprep design team that
I think that this should be moved to 'disallowed' to avoid surprises
like the above. But I'm not sure moving it to 'disallowed' would
solve all problems (assuming that the hyphen is used for concatenating
words).

Regards,   Martin.
