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:
“When I think of the gold-diggers and the Mormons, the slaves and the slave-holders and the flibustiers, I naturally dream of a glorious private life. No, I am not patriotic.”
—Henry David Thoreau (1817–1862)
“The area [of toilet training] is one where a child really does possess the power to defy. Strong pressure leads to a powerful struggle. The issue then is not toilet training but who holds the reins—mother or child? And the child has most of the ammunition!”
—Dorothy Corkville Briggs (20th century)
“After the planes unloaded, we fell down
Buried together, unmarried men and women;”
—Robert Lowell (1917–1977)
