feature #18167 [DependencyInjection] Fix a limitation of the PhpDumper (Ener-Getick)
This PR was squashed before being merged into the 3.1-dev branch (closes #18167). Discussion ---------- [DependencyInjection] Fix a limitation of the PhpDumper | Q | A | ------------- | --- | Bug fix? | no | New feature? | yes | BC breaks? | no | Deprecations? | yes | Tests pass? | yes | Fixed tickets | #17801 | License | MIT | Doc PR | The ``PhpDumper`` cannot currently dump several services' id containing characters unsupported by php.
