Supplementary Private Use Area-B (Plane 16)

U+100000 – U+10FFFD   (1048576–1114109)

The Plane 16 Private Use range was introduced with version 3.1 of the Unicode Standard and requires the enabling of surrogates in Windows 2000; these characters cannot easily be displayed in earlier versions of Windows. There are other Private Use ranges in Plane 0 and Plane 15.

The characters that appear in the first column of the following table depend on the browser that you are using, the fonts installed on your computer, and the browser options you have chosen that determine the fonts used to display particular character sets, encodings or languages.

For this range, the Unicode standard does not specify any characters – anyone can produce a font and assign any characters they wish to the positions in this range.
