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]
