That does indeed produce characters which correspond to the correct
dot patterns in the text_nabcc.dis display table, so far so good ...

Yes, in this case an ancient  Braille Blazer. It's ancient enough I
can't find documentation on its 8-dot display table. Also, IOS 26 has
introduced a new cluster of applications under the Braille Access
rubric. This includes a nice feature for reading files on a braille
device with reasonable workflows for getting them there from my Linux
laptop. Alas it doesn't understand unicode braile so I was curious to
try 8-dot brf. Failed on both counts.

And alas the BB isn't expecting 8-dot brf. Worth a try to avoid buying
a new embosser for the task.
thanks again
