Yes.  With luck, it will just be a matter of regenerating
the tables.  My code for parsing UnicodeData.txt and other
files, and generating the tables, is checked in; I just
haven't tried it to see whether regenerating the tables
is all that's needed.  It can wait a week.

Besides, I should change the table generation to use the
#vu8(...) notation, which will require a minor change to
Larceny's read procedure.
