Right. What does one of those do if it encounters the Unicode braille codepoints? One could say it just echoes them to the device verbatim. But to me, this seems like a movie that's originally in English, but part way through the movie, someone says something in German, for effect. If you then translate (specifically, dub) the movie to German, how do you translate the German? If you just leave it as-is, you lose the "they switched languages here" information that the original contained. Not sure what else you could do. You could inject some text that says "Oh hey user, this was originally Braille, even on visual displays", as an escape of sorts. But for all I know these devices do something like "unrecognized character" and draw the Braille equivalent of boxes.
