If it's a single character on the screen then one backspace will delete it even
if the contracted braille representation occupies multiple cells.

This, I believe, is exactly why Aura would like to be able to turn off
contracted braille and still have all eight dots.

The way I do it for other alphabets (French, German, Greek, Hebrew) is to add
dot 8 to the computer braille representations for the special symbols. For
example, I represent a Greek alpha as dots 18, and a French e with an acute
accent as dots 1234568. And, if you're wondering, yes I add dot 7 for uppercase
as well.
