Unified English Braille is intended to develop one set of rules, the same everywhere in the world, which could be applied across various types of English-language material. The notable exception to this unification is Music Braille, which UEB specifically does not encompass, because it is already well-standardized internationally. Unified English Braille is designed to be readily understood by people familiar with the literary braille (used in standard prose writing), while also including support for specialized math and science symbols, computer-related symbols (the @ sign as well as more specialised programming-language syntax), foreign alphabets, and visual effects (bullets, bold type, accent marks, and so on).
