I think he wants to distinguish a braille 'a' from the regular letter 
'a'. Right now they're indistinguishable unless you use DESCCHAR on the 
whole screen.

My initial thought was to remove the definition for those unicode 
braille characters from the braille table, but there doesn't seem to be 
any such definition.

So the quick solution would be to execute brltty with the
-X lx:unicode=no argument to disable unicode altogether. But then you 
won't be able to use DESCCHAR to identify them either.
