What ▙ means
▙ is one filled tile for terminal art and text graphics. Its usual reading comes from neighboring tiles: repeated blocks create edges, shading, icons, charts, or small images. Alone, it has no agreed conversational meaning.
Block-style semi-graphics were used on Sinclair's ZX80 and ZX81 computers in 1980–1981, when text cells provided a way to draw without bitmap graphics. Unicode's block set carries forward patterns associated with IBM PC Code Page 437, GB 2312, KS X 1001, terminal graphics sets, and Videotex mosaics.
Why do my block tiles have seams?
The font must align every tile and let neighboring edges touch. Block graphics work best when their glyphs share cell dimensions and have no padding between them. A font with unsuitable width, height, or spacing can turn a clean mosaic into uneven bars or visible gaps.
A hollow square, question mark, or replacement box means the chosen font lacks a usable glyph, or the text was decoded with the wrong encoding.
Technical, retro-computing, and decorative; not a conversational symbol.
Uneven font spacing can leave seams even when the character sequence is correct.

1Why does ▙ show as a square?
Usually the font lacks a usable glyph. Use UTF-8 text and a font with Block Elements coverage; if the problem appears in only one app, check that app's font.
