There is no common binary format for "localedata", the file in question is the custom format specific for `BreakIterator`, ancient code from Taligent. IIUC, only description of the format is in the source: https://github.com/openjdk/jdk/blob/2f23c80e0de44815d26a7d541701e16c9c1d32bc/src/java.base/share/classes/sun/text/RuleBasedBreakIterator.java#L325 ------------- PR: https://git.openjdk.org/jdk/pull/12944
