Private Use Area Planes
The two planes 15 and 16, called Supplementary Private Use Area-A and -B (or simply Private Use Area (PUA)) are available for character assignment by parties outside the ISO and the Unicode Consortium. They are used by fonts internally to refer to auxiliary glyphs, for example, ligatures and building blocks for other glyphs. Such characters will have limited interoperability. Software and fonts that support Unicode will not necessarily support character assignments by other parties.

Famous quotes containing the words private, area and/or planes:
“Men’s private self-worlds are rather like our geographical world’s seasons, storm, and sun, deserts, oases, mountains and abysses, the endless-seeming plateaus, darkness and light, and always the sowing and the reaping.”
—Faith Baldwin (1893–1978)
“If you meet a sectary, or a hostile partisan, never recognize the dividing lines; but meet on what common ground remains,—if only that the sun shines, and the rain rains for both; the area will widen very fast, and ere you know it the boundary mountains, on which the eye had fastened, have melted into air.”
—Ralph Waldo Emerson (1803–1882)
“After the planes unloaded, we fell down
Buried together, unmarried men and women;”
—Robert Lowell (1917–1977)
