[BRLTTY] Unicode braille patterns

[Lars Bjørndal]

Hi, list!

I'm working on a project where I need to be able to quickly distinguish
between normal letters and braille patterns in the range 0x2800-0x28FF on
the braille display, with BRLTTY in the console. On
my system, 0x2801 is displayed as dot 1, like a normal a. It's ok if it's
displayed as a question mark or whatever, just for this project. Is
there a simple solution?

Thanks

Lars
