Over the past decade many applications have been developed to aid visually impaired people doing maths. Unfortunately, most of these applications work with only one Braille code, the one in use in the developer’s country. For example, the support centre of my university recently asked me if I knew of a piece of software allowing transcription of LaTeX mathematical documents to Braille. Indeed I do: Labradoor, developed by the University of Linz, does exactly that but produces Marburg code, which is of no use to French students!
