Re: [idn] utf8/legacy versioning

["Soobok Lee" <lsb@postel.co.kr>]

Moreover,

 if "utf-8" is to be a charset, it should have defined the specific set of characters and contains 
versioning tags.

 I suggest:  "utf-8" is an encoding form for UCS. "utf8-8-3.1" and "utf-8-3.2" are charsets names which are
snapshots of UCS with specified encoding form utf-8. This taxonomy would make this situation clear.
Do not forget the set of characters of vague "utf-8" is not fixed from its definition.
