Please let me know more about the characters that
"will never be in Unicode".

I think you say "if gtk+/pango passes PUA charcode transparently
to the font layer, it's enough, no code-conversion issue occurs."
My understanding is right? If so, how do we descriminate:
the fonts which provides expected Hanzi glyph for PUA codepoint,
and the fonts which uses PUA for other purpose?
If there's OpenType feature tag to declare as PUA codepoints are
filled by HKSCS or CNS11643, we can descriminate - but yet there's
no such thing, at present...

BTW, I don't have CJK unifont including Plane 15 & 16.
How do I obtain that?
