Geometric Shapes is aUnicode block of 96 symbols at code point range U+25A0–25FF.

Font coverage

[edit]

Font sets likeCode2000 and theDejaVu family include coverage for each of theglyphs 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 bySegoe UI Symbol and significant partial implementation of this range is provided byArial Unicode MS andLucida Sans Unicode, which include coverage for 83% (80 out of 96) and 82% (79 out of 96) of the symbols, respectively.[4]
