The subscriber in the mqttx software has a garbled code problem

[yizhixia666]

First of all, thanks for your work.
Using mqtt_client, we publish String and Int32 types under our terminal and receive data using mqttx, but there is a garbled problem.

I would like to know if this is a problem with the mqtt-client or the software mqttx?

Please share your exact setup. Which ROS or ROS 2 distribution are you using? What is your config? How do you publish and how do you echo messages?
