The runtime pack shipped ICU's full icudt78l.dat (33.1 MB), and every Intl executable gets a copy beside it. scr_intl.c answers its Intl forms with ICU's break iterators, number and date formatters, calendars and locale IDs, which never read the charset converters or the collation, language, region, time zone name, unit, spell-out and transliterator trees: 21.5 MB of the file. - The pack build writes icudt78l.dat without those items (ICU_DATA_DROPPED in icu-inputs.mjs). filterIcuData rewrites the data file's table of contents to the remaining items, and the result is checked against a pinned sha256 and size (11,653,984 B). - tests/harness/icu-data-filter.test.ts runs every @requires-icu corpus program under 47 locales and 3 time zones with the pack's data, with the full data and in Node, and fails when the outputs differ, so an Intl form that reads a dropped category fails there. - intl-word-segmenter-dictionaries.ts segments Chinese, Japanese, Thai, Lao, Khmer and Burmese text, which ICU breaks with the dictionaries in brkitr/.
