The CIRCLE WITH LEFT HALF BLACK is used to represent the contrast ratio of a screen.

Font coverage

Font sets like Code2000 and the DejaVu family include coverage for each of the glyphs in the Geometric Shapes range.[4] Unifont also contains all the glyphs.[5] Among the fonts in widespread use,[6][7] full implementation is provided by Segoe UI Symbol and significant partial implementation of this range is provided by Arial Unicode MS and Lucida Sans Unicode, which include coverage for 83% (80 out of 96) and 82% (79 out of 96) of the symbols, respectively.[4]

Block

Emoji

The Geometric Shapes block contains eight emoji: U+25AA–U+25AB, U+25B6, U+25C0 and U+25FB–U+25FE.[8][9]

The block has sixteen standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the eight emoji.[10]
