Braille identifiers only make sense when the whole source file has been
translated to Braille. However, the parsing semantics applied to it should
then be determined by the properties of the original characters (before
applying the Braille mapping). If one does want to work directly with a
Braill transcoded stream, then such systm must support *dynamic* property
assignments. That's something that's outside the scope of the Unicode Standard.
In conclusion, it seems that the correct set of *default* properties for
Braille would be determined by the needs of inserting Braille strings into
other text (for educational manuals and similar specifications).
As Marco has pointed out that means BIDI = L and I believe it also means
GC=So, and other properties assigned as they are for other characters that
share BIDI=L and GC=So.
