Braille Codes

Braille can be seen as the world's first binary encoding scheme for representing the characters of a writing system. Today different braille codes (or code pages) are used to map character sets of different languages to the six, or eight bit cells.


The Braille cell

Numbered dots of a Braille cellBraille generally consists of cells of six raised dots arranged in a grid of two dots horizontally by three dots vertically. The dots are conventionally numbered 1, 2, and 3 from the top of the left column and 4, 5, and 6 from the top of the right column.

The presence or absence of dots gives the coding for each symbol.

Braille celll dimensions differ according to the language and use of the Braille code.

Braille for other scripts

Different Braille codes are used to map character sets of different languages as well as for some special uses, such as mathematics and music.

When Braille is adapted to languages which do not use the Latin alphabet, characters are generally assigned to the new alphabet according to how it is transliterated into the Latin alphabet, and the alphabetic order of the national script is disregarded. For example, in the Greek Braille code, "gamma" is written with a Latin "g", despite the fact that it has the alphabetic position of "c".
