/*
* This script updates the `test/fixtures/icu/localizationData.json` data
* used by `test/parallel/test-icu-env.js` test.
* Run this script after an ICU update if locale-specific output changes are
* causing the test to fail.
* Typically, only a few strings change with each ICU update. If this script
* suddenly generates identical values for all locales, it indicates a bug.
* Note that Node.js must be built with either `--with-intl=full-icu` after
* updating ICU, or with `--with-intl=system-icu` if system version matches.
* Wrong version or small-icu might produce wrong values.
* Manually editing the json file is fine, too.
