Since they are sufficient, Microsoft's excess is not the standard by
which to set Emacs's expectations.  (Which expectations must not be set
by proprietary fonts in any event.)

The remainder are, as I said, radicals or obsolete, which are not to be
found in real documents and many perfectly serviceable fonts.

Its not being treated as Kana is a bug in blocks.awk, so this is a
forgone conclusion.  Regardless, this character should be deleted from
script-representative-chars, because on my system it is provided by:

  xfthb:-ADBO-Noto Sans CJK JP-regular-normal-normal-*-16-*-*-*-*-0-iso10646-1 (#x889)

which is not the proper regional variant of Noto Sans (or Serif) CJK for
Chinese text.
