BRLTTY does support it when getting input from BrlAPI clients.
Braille tables in gnome-braille use it too.

Just using the U+2800 unicode range should be fine. Of course, some
ASCII textual hint at the beginning of the document about the language
of the document might help indeed (so as to know whether this is
Japanese or English, for instance...)

There is the U+1D100 Unicode range for plain music. I don't know whether
there exist an agreement on how a record should be written precisely,
but symbols are there to be used.

ASCII is just characters 0-127.

Now, about just braille encoding, there is the ISO/TR 11548-1 8-bit
encoding, which is used by BRLTTY, gnopernicus, BrlAPI, ...

Manufacturers have other encodings, but they are no standards.
