Symfony version(s) affected

6.3.1

Description

Compression of emoji data was introduced in Symfony 6.3 as per #50055.

When I try to compress the data by using the supplied compress tool (running php ./vendor/symfony/intl/Resources/bin/compress), all PHP files in the ./vendor/symfony/intl/Resources/data directory get compressed, except the data in ./vendor/symfony/intl/Resources/data/transliterator/emoji.

How to reproduce

Pre-Conditions

• Intl package installed
• Emoji data was not already compressed

Steps

1. Run php ./vendor/symfony/intl/Resources/bin/compress in the project directory
2. Go into the ./vendor/symfony/intl/Resources/data/currencies directory to make sure that the other files were gzipped
3. Go into the ./vendor/symfony/intl/Resources/data/transliterator/emoji directory to verify that no PHP files were gzipped

Possible Solution

• Move files in the emoji sub-directory up one directory to directly have them in the transliterator directory
• Adjust the compress tool to traverse the data directory recursively to find PHP files also in subdirectories

Additional Context
