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.

Pursued the game with joyful eyes,
Which chose, like meteors, their way,
And rived the dark with private ray.”

Sprouting despondently at area gates.”

Buried together, unmarried men and women;”
