Path is /.well-known/mercure/subscriptions/https%3A%2F%2Fexample.com%2Fmy-other-topic
The current code is transforming it to /.well-known/mercure/subscriptions/https://example.com/my-other-topic
It prevents fastroute to route correctly with the route /.well-known/mercure/subscriptions/{topic}. Maybe adding a test case with my case would be nice?
