I just discovered taht almost all books done in Braille format in English language are created in contracted Braille, and the same thing ahhpens with GErman. AS I don't know this contracted Braille, I wonder me if perhpars there is a program in the App Store and so usable with Mac or perhpas with Iphone as well which allows to converti from contracted into uncontracted Braille in order to e abel to read books with my Braille display.
If you have any other idea, it would be wellcome, of course.
Many thanks in advance. and goodnight.
