MQTT problem with ? in password

[Robert_S]

Hello all,

i want to push weewx messages via MQTT to node-red.

There are no problem when i disable authentication (which i dont want).

Unfortunately this does not work when using special characters (!?) in the password,

which is the case in our MQTT-Broker.

Error in weewx is: MQTT: Thread terminating. Reason: invalid literal for int() with base 10: 'password'

I was not able to escape the special characters, i tried

mqtt://user:"password!?"@

and mqtt://user:'password!?'@

or mqtt://user:password\!\?@

what am i doing wrong?

any hints?

best regards

Robert
