mqtt5-source: Issue with wildcard topic. Character encoding issue? The same topic works with the paho-mqtt5 component

[mikoskinen]

The mqtt5-source seems to have issues if the wildcard is in the middle of the topic. For example this doesn't work:

- route:
    id: route-05dc
    nodePrefixId: route-4ca
    from:
      id: from-c730
      uri: kamelet:mqtt5-source
      parameters:
        topic: test/+/incoming
        brokerUrl: tcp://localhost:1883
      steps:
        - log:
            id: log-ff85
            message: ${body}

The route just doesn't receive any messages:

If the kamelet is replaced with paho-mqtt5, things work:

- route:
    id: route-05dc
    nodePrefixId: route-4ca
    from:
      id: from-5a40
      uri: paho-mqtt5
      parameters:
        topic: test/+/incoming
      steps:
        - log:
            id: log-ff85
            message: ${body}

try with RAW(xxxx) for that value in the kamelet
