Braille Pattern Dots-678

Braille cells make handy pixels for text art. Each braille character is a grid of two columns and four rows, and Unicode includes every one of the 256 possible dot combinations. That makes them a ready-made set of tiny bitmaps: people build faces, logos and memes out of them in comments, chats and usernames, and programmers use them to draw graphs in plain text. ⣠ fills the bottom row plus the right middle dot, so it usually traces the base of a curve or a corner.

Two practical catches. The picture only lines up if the reader's font shows braille cells at an even width, so the same art can look tidy on one phone and ragged on another. And screen readers used by blind people announce each cell by its dots, so a large braille drawing becomes a long string of "dots 6 7 8" for them.

What does it say in real braille?

Nothing fixed; the braille code decides. Louis Braille published his six-dot system in 1829: two columns of three dots. Codes for each language and subject give the cells their meanings, so no single reading applies everywhere. Dots 7 and 8 sit in an extra row beneath, used by eight-dot braille.

Eight dots allow 256 patterns instead of 64, enough to give each computer character its own cell. The idea is older than computers: in 1855 Spain's Royal Conservatory recognised Gabriel Abreu's eight-dot music code. Today eight-dot cells appear mainly on refreshable braille displays, where dots 7 and 8 often mark things such as capitals or the cursor position.
