I'm not sure whether you mean you'll veto anything else or I don't
know what I'm talking about.  Currently:

(let (non-uc)
  (dolist (cs (charset-list))
    (when (and (eq cs (plist-get (charset-plist cs) :name))
         (>= (or (plist-get (charset-plist cs) :code-offset) 0)
                #xf0000))
      (push cs non-uc)))
  non-uc)
  => (eight-bit eight-bit-control eight-bit-graphic chinese-gb2312 chinese-gbk

They're used for things like raw bytes, CJK stuff, level 2, emacs-mule
support &c, and there need to be more eventually.

I don't think it's useful to worry about this and have endless
explanation.  It would be best to spend time implementing and testing,
and I think anyone wanting to work on it will have to read the code
like me.
