No, Braille is not a cipher of any other script. It is *not* simply
one-to-one mappable to/from the Latin script. There are ambiguous
constructs that cannot be back-mapped uniquely. It is in fact a separate
script.
Regarding Moon, my informant last said in 2002: "This is a raised script
used by a small user community in Great Britain." He further said,
"computerized Moon is always read from left to right".
Again, "The Royal National Institute for the blind is the last producer of
Moon texts" and "it is widely read by older blind persons in England."
Nobody has made any proposal for encoding it.
It is English only; and it is a cipher of Latin, except for a few symbols
for word abbreviations, which certainlly *could* be encoded if someone
wanted to take the trouble to propose them. A Unicode implementation would
then use higher level protocol -- a "font shift" into Moon font using A-Z,
with special symbols for the abbreviations.
