How to include \r in the mqtt message?

[helpme1]

I would like to publish a message with \r carriage return character inside. Below is what I did.

mqtt-cli mqtt.test.com topic "mqtt_msg 1\r"

However, the carriage return character is not sent. Instead, the ASCII "\r" characters are sent. How can I put the \r carriage return inside the mqtt message?

Sorry for very late response 😢

I change to read Bytes() not Text(). And, perhaps it may work with using tr to write \r.

echo "FOO _ BAR"| tr "_" "\r" | ./mqttcli pub -t "foo/bar" -s
