Unified English Braille

Unified English Braille Code (UEBC, formerly UBC, now usually simply UEB) is an English language Braille code standard, developed to permit representing the wide variety of literary and technical material in use in the English-speaking world today, in uniform fashion.

Background on why the new encoding standard was developed

Standard 6-dot braille only provides 63 distinct characters (not including the space character), and thus, over the years a number of distinct rule-sets have been developed to represent literary text, mathematics, scientific material, computer software, the @ symbol used in email addresses, and other varieties of written material. Different countries also used differing encodings at various times: during the 1800s American Braille competed with English Braille, in the War of the Dots. As a result of the expanding need to represent technical symbolism, and divergence during the past 100 years across countries, braille users who desired to read or write a large range of material have needed to learn different sets of rules, depending on what kind of material they were reading at a given time. Rules for a particular type of material were often not compatible from one system to the next (the rule-sets for literary/mathematical/computerized encoding-areas were sometimes conflicting—and of course differing approaches to encoding mathematics were not compatible with each other), so the reader would need to be notified as the text in a book moved from computer braille code for programming to Nemeth Code for mathematics to standard literary braille. Moreover, the braille rule-set used for math and computer science topics, and even to an extent braille for literary purposes, differed among various English-speaking countries.
