Right, and that is an upstream issue, so consider to report there[1].

Interestingly the [parent locale of en_AU][1] is en_001. Similarly, this happens for currency names [1]: https://github.com/unicode-org/icu/blob/release-65-1/icu4c/source/data/lang/en_AU.txt Test script: --------------- $bundle = \ResourceBundle::create('en_AU', 'ICUDATA-lang', true); $lang = $bundle->get('Languages')->get('fr'); var_dump($lang); Expected result: ---------------- string(6) "French" Actual result: -------------- NULL ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79197&edit=1
