Contains data of the ICU library.
The bundled resource files have the [resource bundle format version 2.*] 1, which can be read using ICU 4.4 and later. Compatibility can be tested with the test-compat.php script bundled in the Intl component:
php path/to/Symfony/Component/Intl/Resources/bin/test-compat.php
You should not directly use this component. Use it through the API of the [Intl component] 2 instead.
You can run the unit tests with the following command:
$ cd path/to/Symfony/Component/Icu/
$ composer.phar install --dev
$ phpunit
