I would hope we would insist on U+002E (full stop). The idea always was to insist on NFKC normalization, which I would expect to collapse all of those. BTW, http://www.ietf.org/internet-drafts/draft-teint-xidna-base-00.txt http://www.ietf.org/internet-drafts/draft-teint-xidna-email-00.txt have just been published, and if we do add EAI extensions to Netnews, then those mechanism might come in handy for downgrading the Newsgroups header when gatewaying to non-EAI mailing lists. -- Charles H.
