North American Braille Computer Code (NABCC)

January 18, 2026

For literacy braille, and most technical materials such as mathematics my default braille code is UEB (Unified English Braille). That said I still use an 8-dot computer braille code called NABCC (North American Braille Computer Code).

The reason for choosing to learn and use the NABCC instead of the "8-dot United Kingdom Computer Braille Code" equivalent, is simply because it is the default braille table for BRLTTY – a background daemon that provides access to the console screen through a refreshable braille display – that allows me to read text output and navigate the console in text mode.

This makes installing a Linux distro with a refreshable braille display much simplier. I also find that the 8-dot braille code is very useful when working on the command line, to get precise representation of computer-related material such as bash commands, its output, program lines, filenames, passwords ... it's also useful for writing code, scripts, and debugging.

NOTE: The special characters have been arranged as they would be found on a UK (United Kingdom) QWERTY keyboard starting in the top left-hand corner and finishing in the bottom right-hand corner.
