Default break-iterator rules. These rules are more or less general for
all locales, although there are probably a few we're missing. The
behavior currently mimics the behavior of BreakIterator in JDK 1.2.
There are known deficiencies in this behavior, including the fact that
the logic for handling CJK characters works for Japanese but not for
Chinese, and that we don't currently have an appropriate locale for
Thai. The resources will eventually be updated to fix these problems.
