Block Elements is a Unicode block containing square block symbols of various fill and shading. Used along with block elements are box-drawing characters, shade characters, and terminal graphic characters. These can be used for filling regions of the screen and portraying drop shadows. Its block name in Unicode 1.0 was Blocks.[3]

Font coverage
Font sets like Code2000 and the DejaVu family include coverage for each of the glyphs in the Block Elements 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.[4]
The glyphs in Block Elements each share the same character width in most supported fonts, allowing them to be used graphically in row and column arrangements. However, the block does not contain a space character of its own and ASCII space may or may not render at the same width as Block Elements glyphs, as those characters are intended to be used exclusively for monospaced fonts.
