That's IMO not the job of net-utf8, it's not about updating the IANA charset registry, or deprecating (this version of) UTF-7. It is a good idea to do this, and I *think* that Mark Davis (one of the 1641-1642-2152 co-authors) and others also consider these charsets as obsolete or historic. But maybe not bad enough to post a "1641 + 2152 to historic" Internet draft with some IANA considerations about the charset registry. If you feel that it should be done now how about trying it ? In the worst case your draft doesn't make it, no harm done compared with the status quo. > In particular, the registrations for legacy representations of > Unicode should be marked "deprecated" in the IANA charset > registry; to this end, a substantive IANA Considerations > section needs to be added to the draft. AFAIK you can't "unregister" a registered charset, you can only update the registry entry with an updated source (that would be your draft). The source would need references to the old 2152 and 1641 definitions, because you don't want to change or copy the charset definitions, you want to say that the charsets are obsolete and the defining document historic. Users of the charset registry trying to find out what UTF-7 *is* still need to find the definition. I sometimes get UNICODE-1-1 delivery status notifications from old mailers, so it's not yet as dead as you might hope. Check http://rtg.ietf.org/~fenner/ietf/deps/index.cgi?dep=1641 and http://rtg.ietf.org/~fenner/ietf/deps/index.cgi?dep=2152 to see if there are later standards with normative references to RFC 1641 or 2152, if yes this "decruft" procedure could be more ambitious than I think.
