Unicode chart[edit]

The Supplementary Private Use Area-B block encompasses the entire range of Plane 16. The range U+100000..U+10FFFD is entirely designated for private use. The last two code points on the plane, U+10FFFE..U+10FFFF, are designated noncharacters. Consequently, no character code charts or names lists are provided for the majority of this block, except that a chart and names list are provided for the last 128 code points, to show the location of the noncharacters.
