- equivalent but originally unequal
- locale distance shifted left for additional fraction bits with micro distance
- Java more verbose matcher debug output
See #949
- Merge the look-ahead results slots used when multiple rules share a common accepting state.
- Sequentially number the look-ahead result slot. Will eventually allow replacing the runtime map with an array.
- Inhibit chaining out of look-ahead rules. This could never actually happen; when a hard break
rule matches, the engine is stopped immediately, but the state table was being constructed
as if it could happen. Reduces table size for line break rules.
- Remove incorrect handling of fAccepting and fLookAhead fields of a state table row
when removing duplicate states. Look-ahead slot number was being mis-interpreted as a state number.

- Unicode 13 beta data as of 2019-nov-21
- uprops.icu format version 7.7 with more bits for Script/Script_Extensions
- more bits in spoof checker ScriptSet
- root line break rules adjusted for UAX 14 changes, from Andy
- line break tailorings not yet in sync with root
- Updating API status version for ICU4J 65 release
- Fixed a few minor API doc issues in DecimalFormat and LocaleMatcher
- Update ICU4J API change report
These test expectations have been out-of-sync with the output that ICU4J
actually generates for quite some time now. This change brings the
expectations in sync with actual behaviour and makes the test pass.
- StringSegment, ICU4C:
* Moved to top icu namespace
* Compilation unit renamed to string_segment.
- NumberStringBuilder, C and J:
* Moved to main icu namespace
* Compilation unit renamed to formatted_string_builder
* Renamed class to FormattedStringBuilder
- Moves nextPosition logic of NumberStringBuilder to helper class
- remove the old LocaleMatcher implementation code
- move the XLocaleMatcher code into LocaleMatcher, same for test
- remove unused internal methods
- stop comparing old vs. new performance
- generate langInfo.txt resource bundle file with precomputed likely-subtags and matcher data
- make genrb handle multi-line binary values
- load likely-subtags & distance data from new langInfo.res bundle
- test that built data == loaded data
- move data builders to tools, no more runtime dependency on builder code
Get XLocaleMatcher ready for replacing the LocaleMatcher code.
More simplifications beyond ICU-20330 PR #409, smaller data, some more optimizations.
New API ready to be moved over.
- less work for region partitions distance lookup:
- encode each array of single-character partition strings as one string
- look up each desired partition only once, not for each (desired, supported) pair
- look up the * fallback region distance only for the first mismatch, not for each non-matching pair
- skip region distance lookup if minRegionDistance>=remainingThreshold
- locale distance table: remove subtables that contain only *-* with default script/region distance
- mark intermediate subtag matches via last-character bit 7, not also with a match value
- likely subtags data: prune trailing *-only levels, and skip *-only script levels; likely subtags perf test
- likely subtags: skip_script=1; LSR.indexForRegion(ill-formed)=0 not negative
- likely subtags small optimization: array lookup for first letter of language subtag
- defaultDemotionPerDesiredLocale=distance(en, en-GB)
- favor=script: still reject a script mismatch
- if an explicit default locale is given, prefer that (by LSR), not the first supported locale
- XLocaleMatcher.Builder: copy supported locales into a List not a Set to preserve input indexes; duplicates are harmless
- match by LSR only, not exact locale match; results consistent with no fastpath, simpler, sometimes a little slower
- internal getBestMatch() returns just the suppIndex
- store the best desired locale & index in an LSR iterator
- make an LSR from Locale without ULocale detour
- adjust the XLocaleMatcher API as proposed; remove unused internal methods; clean up LocalePriorityList docs
