Category: NABCC (North American Braille Computer Code)

This page was last edited on December 8, 2025

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.
