Regression from commit 14c6cde779:
"tdf#49885 Updated CJK BreakIterator to use ICU"
Previously, languages requiring dictionary-based break iterators were
handled by instantiating a stock ICU break iterator as a special case.
tdf#49885 upgraded our custom rules to support passthrough for
dictionary-based breaking, so this special case is no longer necessary.
