The attached program defines a collation order based on the JIS character
sets which is the most common order used on Japanese platformes. If you
want to support that collation order, you need to build a collation table.
However, it takes 26 minutes to build it with about 7,000 characters on
Ultra-1 (167MHz).

I suspect that the design idea of building a collation table at run-time
is very unrealistic.
