What worked for me in the past:

I imported the http://www.unicode.org/Public/3.1-Update/UnicodeData-
3.1.0.txt text file into a database and wrote simple queries to dump 
the list of char-values and char-ranges for each UnicodeCategory. I 
used MS SQL Server and MS Access as a prototyping-friendly front end 
to write all the queries/formatting code.

In any case, this strategy should work with other RDBMSes as long as 
what you want is the char-values and char-ranges of the 
UnicodeCategory-ies. Otherwise Character.getType(char ch) should tell 
you what UnicodeCategory a given char belongs to.
