Indeed, it seems that people are rather strugling to work around the
current behavior (and have been for years)... Some examples:

- https://bugs.php.net/bug.php?id=40000
- https://stackoverflow.com/questions/68651/get-php-to-stop-replacing-characters-in-get-or-post-arrays
- https://github.com/symfony/symfony/issues/9009
- https://github.com/api-platform/core/issues/509
