 * [Braille Unicode](https://en.wikipedia.org/wiki/Braille_Patterns) — the universal, language independent encoding. It is recommended to use this format for reading with a screen-reader and a braille display. Unfortunately, few braille embossers support Braille Unicode (if any), so it is difficult to emboss a file containing Braille Unicode.
 * BRF ([Braille ASCII](https://en.wikipedia.org/wiki/Braille_ASCII)) — a widely used electronic braille format. Supported by any braille embosser and many braille displays and notetakers.
 * Local Russian encodings (they are developed and used by Russian braille printing houses):
-  * [Logos](https://logosvos.ru) braille encoding — CP866-based encoding that is also set up by default as "Russian encoding" in the [Index Braille)(https://indexbraille.com) embossers.
