The Unicode range 2800-28ff is the "official" way to represent any 8-dot 
braille pattern, but I don't know whether anyone actually uses and supports 
it.  Also I would expect problems (in 6-dot braille) with different 
embossers and page sizes.  Or are you contemplating only reading this 
braille on refreshable displays?
