Update of 23/08/2018 - All online help is now also in English. I translated them using DeepL, an online translator. I'm always looking for an employee native English speaker who can deal with this language; - The default encoding setting in the braille preview is now Generic American; - Removed the Send to Microsoft Word and send to Skype commands... become useless and malfunctioning; - Adjustments to the Unified English Braille 2 table; - New version of Biblos Interface Editor; - French interface synchronized by Elio Medici; - Other adjustments and corrections.
