Unified English Braille

The standard braille code used for English-language literary materials in the United States, United Kingdom, Australia, Canada, and other English-speaking countries. UEB was adopted to replace multiple competing braille codes with a single unified system, providing consistent rules for representing literary text, technical notation, and symbols. It includes both uncontracted (Grade 1) and contracted (Grade 2) forms and is governed by the International Council on English Braille.
