I think that Vim is incapabale of displaying codepoints above U+FFFF, but I'm
not 100% sure. It is a problem for CJK too, since some hanzi are in plane 2
Of course, any codepoints for which your 'guifont' has no glyph (or, in GTK2
versions, for which Xft cannot find a glyph) can never be displayed.
