From reading the javadoc on the Collator strength values, I came to
the conclusion that it should be possible to have a Collator that
sorts "B" before "a" using TERTIARY. But - no. Strength apparently
applies only to comparisons of "a" with "A", other than the javadoc
on PRIMARY lured me into assuming.

The use case: a somewhat generic OR-mapped table widget offering an
API hook to sort by columns. Currently I'm using String's compareTo()
and compareToIgnoreCase() to offer change case sensitivity without
changing behaviour otherwise. Now I'd like to switch to Collator
beause I want umlauts and &szlig; handled properly, and am looking
for a way to avoid expensively toLower()ing before each comparison,
or less expensively but more footprintingly generating some sort of
sort keys.

Ideas anyone?
