I'm no expert, but I don't think it's quite that simple. 8-dot braille is, essentially, computer braille. The dots 7 and 8 were added to make it easier to emboss braille books from the tapes that are used to set print books into type. I think that those extra dots have more function than simply indicating upper case or a control character. ----- Original Message ----- From: "David Allen" <wd8ldy@xxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Tuesday, January 11, 2005 3:48 PM Subject: [bookport] Re: 8-dot Braille Hi to all! Add dot 7 for upper case. Add dot 8 for control chars. Dave
