Description

When attempting to create a database backup via the Web GUI in Craft CMS version 5.4.8, the process fails with the following error message:

Log

The site name contains special characters: d’Humanité. Prior to Craft CMS version 5.4.8, backups worked as expected, despite the special characters in the site name. It appears that since the update, a decoding step might be needed before the backup is created.

Expected behavior:

The backup should complete without errors and be saved to the specified directory, as it did in previous Craft CMS versions.

Steps to reproduce:

1. Navigate to the Web GUI and attempt to create a database backup.
2. Observe that the process fails with the error message mentioned above.
3. Same via CLI: php craft db/backup

We have changed the Site Name to be able to continue working.
