Symfony version(s) affected

6.2.0

Description

In @sulu we try to add the Slugger with Emoji support. Currently the Slugger will hardly fail when the locale is not found with IntlException: https://github.com/sulu/sulu/actions/runs/3554459366/jobs/5970575754#step:10:578

How to reproduce

$slugger = new \Symfony\Component\String\Slugger\AsciiSlugger();
$slugger = $slugger->withEmoji();
$slugger->slug('Menus with 🍕 or 🍝', '-', 'de-at');

Possible Solution

Catch exception in fallback to normal slug for not supported locale.

Additional Context

We currently don't know which locales are supported by withEmoji and which ones not. Which ends up in strange code if we need to handle that ourselves:

try {
    $slug = $this->sluggerWithEmojiSupport->slug($part, '-', $languageCode);
} catch (\IntlException $e) {
    $slug = $this->sluggerWithoutEmojiSupport->slug($part, '-', $languageCode);
}
