Most institutions which produce Braille materials distribute BRF files. BRF is a file that can represent contracted or uncontracted (i.e. grade 1 or grade 2) Unified English Braille, English Braille and non-English languages. BRF files contain plain Braille ASCII plus spaces, Carriage Return, Line Feed, and Form Feed ASCII control characters. The spaces, Carriage Returns, Line Feeds, and Form feeds are sufficient to specify how the Braille is formatted. Previously BRF contained some additional specialized formatting instructions, but now BRF is formatted exactly like Web-Braille/BARD. BRF files can be embossed with a Braille embosser or printed, read on a Refreshable Braille display, or imperfectly back-translated into standard text which can then be read by a Screen reader or other similar program. Many find BRF files to be a more convenient way to receive brailled content, and it has increasing use as a distribution format. If a SimBraille font is downloaded and installed a BRF file can be opened in WordPad, Apache Open Office, Microsoft Word, Apple Pages, etc., and the Braille will appear correctly rendered as 2 dimensional, non-tactile, visual 6 dot braille characters when the font is set to SimBraille.
